If that is the case, don't finalize a trade til Sat and Sun. Doesn't that make sense? lol.
We are trying to weed out the fakers and scammers. So once a trade is "finalized" (ie: I'll give you this for that), you then have 24 hours. If you have a special case where you start on a Monday, but won't be able to finish until Saturday/Sunday, because of work, school, whatever, then let the tradee know, and work it out from there.
Maybe we'll extend it to 48 hours (especially because of the time zones), but any longer than that I believe is unacceptable.
