Cont'd Styling & Group Editing, Hurdle with IDs

Issue: At some point there will hopefully be a lot of users. Until now
I've used a fairly naive way of identifying users / messages, etc using
plain text strings i.e. 'Jake'. The issue is that when people start
adding groups and many people join, using simple identifiers will become
a nightmare. As a result, it would be best to switch now to using
ObjectIds to identify users, messages and groups, but this will take
quite a bit of an overhaul...

I think it will be worth the effort...
