Force subscriptions?

[ayksolutions]

We just recently setup our forum and in order to make it more popular with our users, it would be nice to "force" each new member to be automatically signed up to ALL the forums. The point is that if someone makes a post/reply anywhere on the forum, all the users will get an email regarding it. I believe this will encourage them to atleast look at the forum and perhaps start posting.

I realize that for a larger forum this is not a good way to go as it will eat up too many resources, but a large forum won't need this anyway.

Any ideas?
