(xposted from OpenACS Q&A, but I want to make sure to reach all potential mentors...)
The Tcl/Tk community has been accepted again to Google Summer of Code. In the past, OpenACS and .LRN has been a big component of our efforts and so we again are looking for people interested in mentoring student projects.
If you are interested, please join the Tcl-GSoC mailing list (archives and signup at https://lists.sourceforge.net/lists/listinfo/tcl-gsoc).
Details on GSoC can be found at (http://socghop.appspot.com/gsoc/program/home/google/gsoc2010).
