dr-geo (version 1, C++/GTK) is looking for a maintainer. If you're interested, please take a look at this general information about GNU packages and being a GNU maintainer, and then email email@example.com with a bit about your background and particular interest in the project. Thanks.
Here is the current dr-geo home page. (One task a new maintainer should do is get the main user web pages for dr-geo 1 onto www.gnu.org.)
As can be seen, the original author of dr-geo has made a new version in Smalltalk (still free software). This is very nice, but he says it is experimental. Also, for purposes of the overall GNU system, it's desirable to have a version working with GTK that can be configured and installed in the normal way.
