i dont like this rule:
since there are people who may not buy a membership and want a membership to get higher lvl etc.
so they can only buy it from other people with gigas.
if you are trading it with gigas.
when you are in trade with the other guy.
take screenshot of the trade how you do you screenshot? simple press on print screen and you got a screenshot.
and how to upload a screenshot? simple go to
www.photobucket.com.
www.imageshack.us upload you screenshot there.
after its uploaded take the IMG code and make topic put screenshot and you done.
