Well I think I can help you here
1. Subscribing to the forum means you are notified by email when a new post is made
2. Marking a forum read means that the indicators that show new posts have been made are switched off for you as if you have read them all, the indicatos then get set to on again as new posts are made.
3. I made a change to your account and set "Show
VB code" to On, this will dhow you the bold and italic buttons as well as the smilty input table.
Hope this helps :s5
