I think that the best thing you could do for the Prescription, is to stop asking what the members want you to do:
They wanted a place to talk about general subjects, so you gave them Offshore.
They didn't like the way it was going, so you gave them Bookie Talk.
They didn't like the way people wouldn't go to Offshore or Bookie Talk to play, so you gave them the Rubber Room.
Politics became a charged issue, so you gave them the Politics and World Events forum.
Now they want a place to store "bad" posts, which would suggest to me that they have never looked in Offshore, Bookie Talk, Politics and World Events, or the Rubber Room. If they had, they'd know that there's plenty of storage space already allocated to stupid shit no one cares about.
I love the Rx. The few people I have told about the Rx, as far as I know, also love it. I think that segregating the rooms was a fairly good idea, but that to continue to do so would be a fairly bad idea. So, here's what you can do to cause a quantum leap in the forum's quality:
Charge for membership.
Charging for membership, even a modicum of a fee, would accomplish a number of things:
1) The Rx could either eliminate advertising entirely, or charge substantially more for advertising and limit it to 'exclusive' arrangements with, for example, one payment company, one sportsbook, one news site, etc.
2) 99% of the worst things about the Rx would vanish overnight, as they would never pay for a membership to anything non-porn-related in a million zillion years.
3) The problem with ghost posting, while a small one, seems to really aggravate users. How much ghosting will a given person do when he has to pay for each individual imaginary friend he uses, and a given imaginary friend becomes useless when it's found out and then he has to go pay for a new one?
4) The value of a given member's contribution to the Rx, or lack thereof, would no longer need be tied to the number of hits his threads get.
5) Without taking votes from the posters, let's be honest: you know who is and is not an asset to the Rx. It is a simple thing to just offer them courtesy memberships, and perfectly within your rights to do so -- after all, you own it, not us.
