Personally I believe the admins should do a big housecleaning, getting rid of dead wood (maybe anyone with over 30 posts who hasn't posted in a two years, anyone with under 30 posts who hasn't posted in one year?), as well as dual posters, unless the admins, in their sole discretion, are aware of a valid reason why any one presence should have 2 identities.
PS Hey Lawrence, forgive me if this is a dumb question, I don't know how this stuff works, but would that help save some bandwidth if you hauled away the debris?
No problem. It has been mostly answered already - but I'll add this, we have thousands of members who register and never make a single post - but we see that they login and read. There are features that are disabled in guest mode - so many will register to view - pictures or classifieds or whatever. From time to time, we will remove accounts that have dead email accounts.
