Also, the last Saturday September 13th, Claus Gittinger had been in a meeting of the group Smalltalking in Buenos Aires. Here you can read a blog post of Angel Lopez about the meeting where he talked about Smalltalk/X.
Since 2004, ClubSmalltalk is a non-profit organization which congregates Smalltalk programmers and enthusiastics. The big idea behind this website is to provide a source of information about Smalltalk in general.
The Smalltalk community has not good sources of information, or they're all over the net, and sometimes it's difficult to find them.
If you want to contribute, you're welcome!
