Hi,
This is the first time I have heard about the error you have faced while posting on the Boards.
Thanks for bringing the same to my notice. If you happen to face the error again, I will request you to mail me a screenshot of the error, URL and what you were doing before you received the error. It will really help us in understanding and fixing the error.
Also, since Discussion boards are maintained by a company called Live World, an eBay error will normally not effect Discussion Boards.
Thanks,
Sapana
