Currently the board is set that unless you are active (browse a new forum, read a new thread etc) within a 15 minute period you will be automatically logged off. The reason for this is that most people don't click "log off" when they exit and without this feature they will stay logged on. Problem arises if you are writing a long post, and can be disconnected before your message is saved. I can extend this time if it is a problem for anyone, but please keep this limit in mind when posting long replies.

Thanks all

Great!

It takes me more than 15 minutes to read a thread sometimes.
Will that kick me off as well?

well - it can be set for longer, but should you exit and not log off the someone posts, the board will assume you saw that posty and when you return and click "new posts" it wont show up. 15 minutes is pretty normal.

You can stay logged in by staying active - clicking a link every ten mins or so.

When you do get "kick off", you can still read the posts/thread and browse the forums normally (unless you have special access somewhere), but you cannot post replies/new threads unless you're logged in.
