I just got my first Android phone, the Samsung Galaxy S 3. This is my first experience with the Android app and I'm still getting used to it. I know on the iPhone app you could touch a post and see the members sig. It doesn't seem to work the same way with the Android app. how do you look at peoples sig?

Also, why can't I see anyones avatar including mine?

I have the mytouch 4g and I can see the avatars but I can't see the sig. I don't know how to see the sig.
