What does 'Register' do for a G1G1 user?

[Mikus Grinbergs]

The 'Register' that shows up on the drop-down menu on the Home view 
- I always thought it was for a pupil to "register" with his school 
server.  But I have a G1G1, and __no__ school.  [I don't have any 
wireless, either.]  Is 'Register' supposed to do anything for me ?

p.s.
[Looked on the wiki.  Did not find anything that described 
'Register'.  Did not even find anything that talked about
needing to register (or not) with a non-school server.]
