[om-list] modeling software

[Luke Call]

Flu, holiday, &c. have kept me from doing much in the last couple weeks. 
I tried using Together, the modeling tool written in Java that I had 
recommended, but found you have to buy the $2000+ version (non-free) to 
create things like collaboration diagrams; the free edition can only 
view them, or create just class diagrams. But I found a better one which 
is under a BSD-like license, called argoUML, which has much better 
features, free, open source, etc. It can do almost everything in UML 
1.3, is cross-platform (again, written in Java adn looks pretty good). 
Maybe class diagrams can substitute for ER diagrams? Available if you go 
to www.argouml.org. I'm interested in any thoughts....
