Me too bro.
I could post a link to one of my other sites, but when I tired to post the other one it wouldn't work.
Pisses me right off.
I have found that when you do an advanced search and start posting is when you are most likely to get the error.
I can post all day if i'm constantly refreshing or looking for questions that match my posting criteria, but the second I start doing advanced search for my terms I only get like 4-5 posts out before I get this error
