comment Beginner or intermediate skis for a first pair to buy?
This question is close to what we call a "shopping question". Such are normally closed because they tend to get outdated rather quickly. However, in your case it looks quite easy to rephrase it such that it doesn't refer to a special product any more but asks the more general question what type of ski to buy in your situation. Maybe you might want to edit it that way?

comment 1000 names for snow
@Venture2099 Agreed! Nontheless, a nice community wiki collection (to me this is one of the really rare cases where a community wiki would make sense) of the different names would be some nice feature.

comment Why don't people in the UK use snowshoes?
@Aravona They work on both. The only snow that is kind of ugly to ski is wet slushy snow as one might experience it on warm days or on sunny afternoons. This is the reason, why ski-tourers tend to start early ;-)

As I know that you are able to understand German, this one might be helpful: bergundsteigen.at/file.php/archiv/2008/4/print/… I will compile an answer based on it tomorrow as I will have more time then.

@mattnz sounds a bit like swapping drinks if you fear that the other one has poisoned yours ;-)

comment Is there a recommended safety standard for crampons?
Maybe as a side note: I have never read that crampons must meet any standard to be allowed to be sold. Climbing safety equipment (biners, ropes, etc.) may only be sold in the EU if they have the corresponding EN standard certification and have to be marked if they look like real climbing equipment but aren't certified. I did never hear such about crampons, so it may be allowed to sell them in the EU even without certification.

As far as I'm concerned, you cannot delete it, it can only be closed.

comment Is it a bad idea to dry clothes by the fire?
@LS OK, let's restrict it a bit: the rock will not explode just from putting typical undies on it" (corrected typo as well ;-) Of course I cannot say for sure if this is true for Jason's steel undies as well.

"a rock would definitely not explode"... well, they do, if you get the wrong ones: outdoors.stackexchange.com/questions/801/… and outdoors.stackexchange.com/questions/1407/… However, the rock will not explode just from putting your undies on them.

comment Best technique to sharpen a knife using a whetstone?
If you rub some metal over the roughest stone, the metal will have scratches that can easily be seen with the bare eye. To see the scratches left by the semi-rough side you will have to look very carefully, maybe with a magnifying glass. Both of them will make some scratching noise when worked with a metal. With the fine and super-fine one will at first glance not guess that it is able to do any harm to a metallic blade. Their noise is more dull, like rubbing two very smooth surfaces on each other.

comment Best technique to sharpen a knife using a whetstone?
It depends a bit of the grain sizes of the stone, whether you need the rough side at all. Basically such two-sided stones often come in two versions: one with a rough and a semi-rough side (grain sizes around some hundred grit) and one with fine and super-fine side (grain sizes in the thousands). With the rougher version, the rough side is normally only needed if the blade edge was damaged and has to be rebuilt by grinding bigger amounts of material until it is free of notches.

comment What are areas of the body which lose heat more quickly, and how can I reduce that loss?
I tend to contradict in 2 points: spots that feel cold first are not necessarily ones that lose the most heat but can also be areas that have low insulation and/or blood vessels close to the skin. Especially the wrists (also the veins at the thigh inside) are known to be well suited to manipulate body temperature sensation by "feeding" heat or cold into the body. This does not work because they are spots of heat loss but because they allow easy thermal coupling from the outside and the blood flow transfers the temperature applied there quickly to the body core.

comment Why some sleeping bags have four temperature ratings while others have only one?
possible, yes. At least you have to assume that the figures given are more or less useless or not comparable. As Ryley stated in the answer I have linked, they might write a rating at their bags which they expect protects them from being sued for, plus some error margin.

comment Arm compression sleeves for climbing
I still do, as the question was "Are there anecdotal or actual studies on the effectiveness of forearm compression sleeves for climbing?" Also you state that "Veins are through internal segments of the body and Arteries are in the outer segment" but according to my knowledge and Wikipedia it's reverse: "Veins are [...] often closer to the skin [than arteries]."

Sorry, but I don't see at all how that tries to answer the question...
