Well, that's something very easy to do
Try the Extra Boxes Mod (you need the Guest Information part, where you can put the info you want to show to your guests).

Well, of course you can put a big ATTENTION sign image on every page and make IE alert them on every submit that they're not registered and they should do so, but that's just plain annoying. I think it depends if you have a community forum (where most of the talkers are registered and form a comunity) or just an informational forum (where most users are guests, they come, read the info, maybe post something and leave).
As for the announcement, I think the extra boxes mod can be modified very easy for your purpose (to add a line to the top of the normal announcement saying to the uregistered users that they should register).

Or if you have SSH access to the server hosting your forum, try :
chmod 777 cache
