Administrative Member Report "files"

[FlyBoy73]

I am looking for a custom hack that will allow moderators (and above) to make a report on a member - generally one that is having "problems".
This report would then appear in the user's modCP and adminCP profiles where it can be looked at when something else comes up in the future.
So, if Member X got into trouble, a moderator could click on their postbit (or someplace else) and would get a entry form where they could state what the problem is in detail, and what they did about it (Warned, etc).
Their file in the mod/adminCP would contain the Mod/Super Mod/Admin who entered the information, Time & Date, Action Taken and maybe a severity level?

How does this sound? Would this be hard to create?

I just need a way to keep record on individual members in their profiles (supermod/admin only viewing - may admin only?) so in the future, if there are more problems, we have a good record without having to search forums and my memory.

This hack could also record positive actions that mods + observe.. And assist and chosing good candidates for moderator and administration.

Thanks!
David
