gorbachev, if you are not seeing your proposed trades on the website then that does sound like a bug. Please send me an email to email@example.com, and copy and paste the following:
I can't create any trades at the moment. I select cards for both parties of the trade and hit the Offer Trade button. Trade seemingly gets created, but it's not showing up on the pending trades list. Whether the trade actually exists or not I can't tell. I use the web interface only, "gorbachev" in the forums.
Email from your NeonMob connected address and that way we can easily access your profile to determine what is happening. Thanks! - Joe @ NeonMob
