Do not think about it, but if it meets my requirements, I can install it. As I understand it's more for members' rankings, you've been a member so XXXX long you'll get this XXXX rank. Have you written many XXXX posts so you get this rank.
If you are referring to the auto groups extension Toxyy mentioned, the answer is no.
Ranks have nothing to do with groups. Ranks are a default phpBB feature to be found under ACP - Users and Groups - Manage Ranks. That's were you can define a rank and the postcount threshold, plus a specific image if wanted - completely independent from Groups.
The auto groups extension is an Extension, thus not present in phpBB by default, and it provides a new functionality which is automatically adding users to a specific group when certain criteria have been met.
