I just discovered all of the social features of the site. More importantly I just discovered sister sites like
android.stackexchange gaming.stackexchange unix.stackexchange
When I went to android.stackexchange, it shows the Login link instead of my Username, on the top mid/right. So I clicked Login and chose to use my SE account. However it is not accepting my email address as valid even though my email is properly listed on my profile here.
Can anyone tell me what I'm doing wrong?
Edit: Sorry for not clarifying. What I'm trying to do is to sign up using my Stack Exchange account. It isn't accepting the login that I use on ServerFault, though.
