Well, there are 3 different groups at this forum named "member". If you look at the member's list, and search for each group, there's one containing all the members with posts lower than 50 (in order to get to the member's only tutorial section), one containing all the members who have 50-299 posts, and one with all the members that have 300 and above.

I know what the 50 landmark is, but what's the 300?
