Modifications Suggestions

[Majest]

I couldn't find the suggestion forum that once existed here (at least I recall there was one at one time) so I decided to post it here.

I have been looking for two simple modifications (at least simple to those who know what they are doing).

1. Delete User but Keep Username or Delete all Posts
   In a nutshell I am looking for a mod so that when you delete a user either their posts keep their username instead of becoming guest or all their posts are deleted with their account/profile.
   
2. Easy Large Scale User Profile Deletion
   I am simply looking for a mod that allows a admin to do mass deletion of user profiles like one can with threads on the forums. I like to delete zero posters after a certain amount of time and I have 900 members at the moment with at least 600 of them being zero posters.

I do believe these modifications would be extremely handy not just to me but many other admins on various vB boards out there and save us all a lot of time.

I would be great appreciative and thankful if anyone could construct such modifications.
