Bob, the posts are good for 90 days then deleted. When the posts are deleted, the poster is welcome to post again. They are in order, newest to oldest. After the 90 days, can you see me going thru the posts and looking for outdated posts to delete if we allowed BTT ? I can't.
They would be in no order and it would take time I don't have to spare.
You are able to track how many times your post has been viewed by looking at the right hand column.
With the way the free forum is set up, it's the best we can do.
