Great :-)

You can use the current_user variable which is available in all views. 
If you're using it to get the username you will need to first check if 
the user is logged in. So, for example:

Name: <%= current_user.name if logged_in? -%>

(or using current_user.username in your case).

This could potentially pose some problems. You could write a db migrate 
script to add this field but then the numbering of these scripts could 
get messed up when you pull down later revisions (as you suggest). You 
could just do this and then manually renumber subsequent scripts, though 
ofcourse this isn't ideal. Alternatively you could modify the database 
directly, bypassing the db migrate scripts? I'll see if there are any 
other options you can take...

As an aside, in Rails 2.0 instead of numbering there is the option to 
use timestamping, which allows you to intersperse db migration scripts 
and rake db:migrate takes care of running any scripts that haven't been 
applied, and of course there wouldn't be any clashes in ordering.

Cheers,
Jits
