Whats happening ?

I think there is a major delay when posting a message.

It sends but then says it doesn't exist ..and isn't there...
..but then appears a short while later complete with all the times I was hitting 'post!

That could be many of things.

1. Your internet connection may have timed out during the process
2. The server had timed out
3. The SQL database may have been slow and cause the php script to error
4. Posting too many times would mean you repeatedly kept pressing post causing a que on the server

These things happen and not much can be done form my side about it.
Sorry
