Mod or MySQL query to auto subscribe all peoiple to all threads

[tnedator]

I have a small forum that is used for internall discussion at work. We only have about 20 members of the forum, and it will stay at that size.

What I need to accomplish is to auto subscribe all forum members to all new threads, as they are created, so they don't have to manually subscribe to new threads via the menu or replying.

So far, I have not found a mod to do this, so I was wondering about a sql statement.

Can someone help me with a SQL statement I can run with a cron job every five minutes or so, that would subscribe all forum members to all threads?

Thanks
