Hey David and all others who want to contribute to GSoC,

the ASF has applied for GSoC 2011 as a mentoring organization. As a
ASF project we don't need to apply directly though but we need to
register our ideas now. This works like almost anything in the ASF
through JIRA. All ideas should be recorded as JIRA tickets  labeled
with "gsoc2011". Once this is done it will show up here:
http://s.apache.org/gsoc2011tasks

Everybody who is interested in GSoC as a mentor or student should now
read this too http://community.apache.org/gsoc.html


Thanks,

Simon
