it would be no great loss to lose a few of the earlier posts.
small price for a tidier more manageable site
It is evident you want a more manageable site, but would losing a few of the earlier posts really make it a more manageable site. I really don't know what kind of management you do to this site. I do manage a website for my church but it is definitely not nearely as extensive.
Let's say you do delete some of the earlier posts...Would that really make it more manageable? What management does an old post need? It would definitly be a little bit tidier.
I am just trying to weigh the pros and cons.
If you want less to manage, I think you would have to cut back on threads not just posts. I do enjoy the tavern threads, but I can see how they don't relate to the site. The taverns are for enjoyment aren't they?
I suggest deleting the old old threads that are at the bottom of the lists. The ones no one has replied to for years. Delete those. Most the people who posted in them are gone and only had a few posts anyways.
(This is my opinion. If I am way off base you can just neglect my statement.)
