Thats what i figured. I saw both of them because i only ever do two buttons on pc - My Profile, which shows me new updates to threads i have subscribed to, and New Posts, which shows me new posts to just the forums i subscribe to in Edit Profile.

i exclude forums like Games which generate waaaaaay too many posts for me to deal with daily. I was doing Games for a while, but i go there directly if i want to. Also sex and stuff - eww! I mean i skip that!
