^ I think probably the way you are thinking would defeat the purpose. To just delay the messages would still allow a spammer to bang out like 30 spam posts and just send them all at once and watch them appear one at a time every 20 seconds.
Sestak - what about reduced to 15 seconds? It's not much, but the feature is for anti-spam, so Dave wouldn't want to get rid of it entirely. I made new anti-spam stuff so this 20 second delay is less useful now imo.
Also, good idea HCP
My biggest annoyance is that I have to
wait 20 seconds after logging on. If it could be modified to only be between posts, I'd be happy.
