{great Idea] Present/Absent log system for Mods

[asasi]

Hi
we have a topic in our moderators and admins forum and mods each day post that he/she is present. but its too unprofessional.
I think it will be very cool that vb will log moderators detailes like these:
1) each mod was online in each day
2) how long he was online in each day
3) how many posts in each day

if these log works for one month ago it will b very cool.

thanks a lot
