This is a good time to submit more new proposals for the IETF! Our meeting in Prague is coming up in July, and the proposals for new working groups ("Birds-of-Feather or BOF sessions") are due this Friday:
http://www.ietf.org/meeting/important-dates-2015.html#ietf93
Please contact your Area Director to ask for help and read RFC 5434 for more information on how to create new working groups at the IETF. And of course, new working groups are usually for bigger and fundamentally new proposals, while much of the ongoing work goes on in the existing working groups. If you have suggestions around any of the protocols that we are currently working on, let the working group know by posting on their mailing list.
Looking forward to seeing you all in Prague!
Jari Arkko, IETF Chair
