Looking great, Lori.
Krystyna, to subscribe to a thread, go to the Thread Tools tab on top of the thread to the right. And choose subscribe, the third option.
Don't forget to go to your General Settings (you get there from The Settings tab on top of page next to your Sign Out tab or by going to Forum Actions tab on the center of the top tool bar) and make sure you set your settings to how you want to see your subscriptions, email or under panel or whatever. From there you can also choose to automatically subscribe to threads you reply to. Hope this makes sense.
