I guess JimRob put some money into a new server to handle this, and other undead threads...
Well..
When threads got above 30k posts, the server tended to have issues.
So we stopped doing that and began moving on a month to month basis.
It was an effort on our part to NOT crash, crush, spindle, fold, flibble, or otherwise rankle the servers.
Since I haven’t been on a thread that got above 5k posts in awhile, I don’t know through observation what will happen.
