Error: Posting this fast is considered spamming, you are warned!
You are only allowed 98 more attempt(s) after which you will be banned as spammer!
if this is considered a bug, I could reactivate my account at YaBB and file it there.
Edit: I just posted this at yabbforum.com and it seems this behaviour can be adjusted. They also have the wait... feature, but it timeouts much faster (5s or so).
