Thanks for the information. .. How many posts can be done daily? is it according to the rank or something?
Indirectly yes. You have a post limit that decreases with higher activity. E.g. a newbie can only post every 360 seconds (5 minutes), while after a certain activity you can post every 4 seconds (you shouldnt though). Besides that, there is no limit to the number of posts you are allowed to make as long as you dont spam.
# keep the posts ontopic even when others try to derail the topic
# make sure you read the entire thread before you answer (or at the very least the last few pages of a very long thread), giving the same answer over and over again does not help anyone
# if you state your opinion on something, explain a bit about why you have it. Dont post "I think x is y", but rather "I think x is y because of a".
# dont copy someone elses posts (perma ban w/o warning)
