[Pythoncard-users] Re: Pythoncard mental block

[<gre...@gm...>]

The Python-Card guys are really helpful, <
pyt...@li...>, you may have to register on
sourceforge to get on their list.

In the meantime I went ahead and cc'd them on this. Python-Card guys, make
sure to cc Steven as he may not be on the list.
