I think it went from 30 seconds to 60 seconds though, I have experienced the 30 second reply cooldown on a previous account, also thank you @Hooksmith for providing the answer as to why I am getting this popup
The staff are planning to make the Regular trust level not differ from the Member trust level as they recently released the @AllowBugReports group, Here is the announcement, and I had seen some regulars doing some spam on the forums, and reducing it for regulars sort of defeats the purpose of the reply cooldown
though the best bet to deal with the reply cooldown is to either write longer [which I am now doing for this account] or wait 60 seconds to reply
