I was wondering if someone could refresh me on how to take a snap shot and then what to do next for trading in D2?

here you can watch everything up ingame / and jsp screenshots

you can upload on Tinypic.com for example

press print screen
if it's a d2 screen just go to tinypic to upload it
else copy your s/s on paint and save it then upload it

press "prnt" on your keyboard
paste the screenshot in paint / if it's at d2, simply check your d2 folder
save the picture
upload at imageshack / photobucket / tinypic

For a mac:
Apple + Shift + 3

For Windows:
Print Screen(located above Insert, Delete, Page up, etc)

You can upload on this website for the most hassle free: http://imgur.com/ No account required.

It's not a mac sorry, but thanks.
