I think it is a good idea to combine a couple of events. However, I would suggest an agenda so that people of each respective interest group have an idea of what will be discussed.
There is currently discussion ongoing on the MumPy (https://groups.google.com/forum/#!forum/mumpy) and the MumJS (https://groups.google.com/forum/#!forum/mumbaijs) Google Groups about topics. They should be finalised in the next couple of weeks. I will cross-post a summary of that discussion here, once it has been finalized, so that everyone here knows which topics will be covered by them.
In the meantime, we can get our agenda fixed. Please share suggestions on this thread.
My suggestions about activities for the Mumbai LUG meeting and Ubuntu Release Party:
1. Showcase the features of Ubuntu 13.10 (desktop, server) 2. Showcase your FOSS project (maximum 3 projects can be showcased due to time constraints) 3. Spotlight: Showcase a GNU/Linux distribution (other than Ubuntu because that will already be covered!)
