There will be no sub forums, I like one forum for everything, just like joe's forum, trust :)
How do you mean? There are A LOT of options in your profile for email subscriptions. You can change your profile so that the site emails you after you comment on a post...and I think it is possible to get daily and weekly updates rather getting 100 emails a day.
You can also select "subscribe to this thread and notify" to a thread under "go advanced" when you start a thread or reply to one.:D
how do you resize photos to post?
Can we increase the size of the photos allowed?
