Is there a UML: How it Works for Developers - document somewhere? or must we be so dedicated that we browse the mailing list archives and look for explainations piecemeal as responses to queries (as we've seen recently on the list)? appoligies for any toes i'm stepping on here - i want to help - i just need help to get there...
