How do i take a screenshot?

I just finished my Frost Dagon guide (well, sorta just) and I want to include pics of armor and weapons loadout, but the problem is,I don't know how!! XD Please help!

to take a screenshot, it's simple just click prtscreen and copy and paste in your paint.
if you mean how do you upload one, just go into make a topic and just above ^ will be a few boxes, move your cursor over them and find "image" or...
"host an image" one of them works and if that's wrong and you have a url from imageshack.com or something click insert url hope this helps haha

I suggest, downloading prntscrn before trying to use it lol. or you'll just look silly pressing the button and nothing happening :p
