bug reporter emails

[Graham Percival]

Hi,

What should we do about storing email addresses of bug reporters?  The 
CC field of the google issue tracker looks very inviting, but it only 
allows google user names there.  :(

So far I've given people a link to their bug, so they could bookmark 
that and check it whenever they want... should we also encourage people 
to get a gmail account so they can get all activity on their bugs 
automatically CC'd to them?

I'm not going to keep a bunch of old bug reports in a folder and hunt 
for them when bugs get resolved.  I suppose that I _could_ find their 
email address from the "comments" field and send them an email, but I'd 
rather have some kind of automatic system.
