I have a reader on my blog that has been posting for a few months with no problem, suddenly he can no longer post.
I am thinking that I may have accidentally marked one of his posts as SPAM and that blocked everything he does, but I can't figure out how to unblock him (if that's what it is).
He was posting as a non registered guest, but I had him register and still no luck.
BTW, I am running 1.5
Any ideas? I'm stumped.
