I volunteer if the talk is in Spanish for the local people, and the stuff to be talked is more developer centric, like in what resources has maemo.org for developers, etc. (of course, I would talk about some user stuff like Talk, or the Wiki, etc., but it isn't my topic of expertise).

I don't have much time this week to do the presentation, so it'll be very plain and simple

Of course, this all depends if the talk is in Spanish, if it's in English other people can to do it better than I.
