I was rebooting some servers while applying patches last 2 days. If you were on when I was doing this the load balancer pops you to another server and you loose session. this can cause this. if you type any lengthy reply you should copy it right before you submit just in case something odd happens. this should be rare but while we are in maintenance it can happen (or if a server is having issues).

we are upgrading our forums shortly and it should fix many issues, add many new features long overdue and add additional stability
