I can't seem to find out how to do it anywhere...How do you find out how long someone has been a member of a team? I'm doing badges, and I need to double check a few people.

At the top of the sreen it says:

Memberlist

It says when everyone joined. Though there are over 80 pages....

He wants to know how long someone has been on a team. The Memberlist shows how long someone has been a member of the forums.

In case you were wondering, yes, I checked USERGROUPs, it doesn't show it.

And, yes, I need when they joined a team, not the forums.

One way to check (although it's kinda unreliable) would be to do a search for posts by that person, limited to the team's forum, and sorted by posts date (ascending). That would tell you how long ago their first post in the team's forum was, which should be pretty close to their join date.
