Once you are Jr. Member you wont have any problems. The higher your rank, the shorter the waiting times
IIRC, around the point of about a Member the minimum time between posts is small enough that you won't get notices telling you that you can't post unless you are literally spamming a new post every couple of seconds. I'm not too sure whether it gets lower from there on - has any of the staff ever mentioned it for the higher levels?
It gets lower each activity period. Out of curiosity I tried to post 2 times straight away. The restriction for me seems to be 11 seconds.
hmm. I guess 11 seconds is the lowest then? Maybe its because it was on a same thread? I dont know..
the minimum is 4, happens when you get 500 activity or more. See my other post here
