You may only ask for trades in your signature or by making one trade thread on
this board. Your trade thread is
here. You can edit your post and topic title if you change what you are looking for. Posting that you are looking for trades anywhere else on the forum is spam and not allowed.
Additionally, you may only bump your thread once it has fallen off of the first page of the forum that it is in. That can take 5 - 30 minutes in the trade board depending on the time of day.
