If you are tired of PM's, then it is a problem within your means to correct. No need to rewire the entire forum to solve a personal issue.
The easiest solution would be for all of the ES "celebrities" unhappy about being popular to create new accounts and change their user names. If you want to be a rock star, then you have to deal with the publicity. Of course then no one will know how cool you are if you don't have an ego-stroking billion post count nuke next to your name.
Docbass, this post was not a personal comment against you. I am sure that it probably does get maddening and you DO want to help, but it surely becomes overwhelming. The solution is simple enough, after a few posts with a new identity, those who need to know will figure out who you are. You could post daily as "Clark Kent", then save your "Superman" persona for posting about your record-breaking attempts etc. Also, this forum will allow you to disable contact via PM's and e-mails, another idea for those your "Docbass" persona, but your "Clark Kent" persona could still receive messages.
On another forum I frequent had a frustrated "Rock Star", he set his account to contact via e-mail only, then set up his email acct. spam filter to reject problem messagers.
I get questions about the Keywin programming sticky I made fairly often. I got tired of it and added info to the post basically telling folks to NOT send me PM's about it, unless it is a change needed in the instructions. Every PM I get about it now gets a stock reply of-"I don't know, ask the forum."
Anyone with an issue or question about this post should send a PM to Docbass about it.
