Often instantiation provides some kind of customization that makes instance different from other instances. If you do that for your users, they won't be able to customize their instances, unless you provide a separate 'initialize' method, but then it's just as much work for the users to use that method as compared to passing args on instantiation. So, how many instances do you want to make.. what kind of different functionality / properties they will have? - mitya -- Lark's Tongue Guide to Python: http://lightbird.net/larks/
