You can follow anyone from their usename. If you look above you will see your username "dek". If you press on it it will allow other users the option to "FOLLOW". I just followed you. It is courteous to follow someone back when they follow you. Go ahead and try it on mine. You may need to refresh your page to see results.
I figured that out, but following people from their profile doesn't seem to always work. I tried following you from your reply here, and it worked. Thanks for the input, though, I appreciate it!
