DebConf11 call for contributions

“We invite submissions of proposals for papers, presentations,
discussion sessions and tutorials for Debconf11. Submissions don’t
have to be limited to traditional talks, you could propose a
performance, art installation, debate, or anything else. Official
submissions will be accepted until May 8th 2011, 23.59 UTC.

“This year submission of a formal written paper for the
conference proceedings is again optional, though encouraged.
Providing a written paper in advance means that interested people
can attend your session ready with ideas for discussion, and
especially helps those who find it hard to follow rapid English
