Sounds interesting. I think it would be interesting to know in greater
detail what and how you're using it (and how others are using it as
well). I think that the UML community would benefit alot if more and
more people share how they're using it and how's it's benefiting them
including detailed examples.

I mentioned this in my previous thread and Jeff redirected me to:
http://uml.harlowhill.com/ Unfortunately, it's read only. The problem
is that for anyone to share their experience, notes, tips, etc, they
would have to post it on their own site (if they have one). Even then,
it would mean that you have to search and try to find these web sites.
It would be great to consolidate this information into a single
knowledge base. I can understand that Jeff's too busy working on UML to
bring us more features and better performance :) to have time to
maintain the wiki more regularly and to allow edits, etc.
Unfortunately, I have almost no wiki experience so I can't really help
