Im trying to do a rate and review and this is whats it says
The Subject must be an accurate description of your post.
Subject of Posting: ju1234
Got my seeds,thanks.
Just for fun, I attempted it and got the same message. I suspect it is a GW fluke that won't allow the subject line to just have 2 alpha characters, and the rest numeric.
I tried it making the 'Subject of Posting' line...
ju1234 (member trade) and it looked like it would have been accepted if I'd chosen to 'Submit'. I'd suggest trying it that way, or something similar without posting anything positive or negative in the Subject line.
