Active members mod

[RustedBucket]

Is there a mod that is similar to who's online but shows total active members within a timeframe or a way I'm not figuring out to get this?

Basically if I have 10,000 members, I want to know how many of those have been active within say the last 30 days.

That's a feature of vBulletin that simply needs to be turned on in your vBulletin options.
