redirect ?

[Bigguy]

This might be a dumb question and I really couldnt find anything pertaining to this specifically so I thought I`d post

Is there away to make it so that when ppl login to your forum they get redirected right to the "Announcements" board on your forum (If you have one) But only have it this way when there is an important announcement that concerns everyone so no one that logs on can miss it. So I guess it would have to be able to be turned on and off in the admin section. has this been done yet or .... ?
