questions on possibilities to analyse a forum

[jdi]

Hey, I've come across some questions while working on our forum. For a future update and integration of plugins I'd like to ask for some tips on how these things could be done...

Can I analyse threads to see if a moderator is involved? Could I get a ratio of moderated threads against unmoderated threads?

Can I see (per day/week/month) how many registered users have been logged in and/or posted? So I could get an overview of active/passive users.

Our forum is divided into 3 subforums (german, french, english). Can one track visitor numbers per time separately for each?

Can I get user-specific analysis? So to say how many posts per day/month... has he done?

There is this hottest thread statistic. Is this possible per week/month?

Can I only get the number of individual visitors for a thread, so users visiting multiple times are counted once?

Any ideas?
