I hadn't heard of this problem before and I've not seen it happen myself.Does it usually happen only during longer posts or does it occasionally happen during quick replies and posts also?
For the record, I've logged in once, when I joined the forum. I haven't had a validation or time-out issue at all since I joined....
One thing to consider: Find out what browser the various affected and unaffected people are using. I use Firefox on Mac OSX. The browser or operating system may be what is making the difference....
(Almost to my 100 posts.... I just need to think of a couple more things to say...)
You mean like replying to posts which didn't actually ask a question, open a debate for discussion, or require any particular response?
