If 'hypothetically' one existed that had the following features:
* Allowed posting from your server.
* Allowed you to add the forums you wanted to post too.
* Could store messages for delivery at a time YOU set.
* Worked on VBulletin and phpBB.
* Could group boards together by forum category.
* Could post to board groups, individually or selected forums.
* Could post to a hundred forums in less than 30 seconds.
Finally a good email to use if you wanted to order such a script would be
boardbot@hotmail.com
