Generally anyone with an interest in development of the XMPP protocol is welcome ?
This year has been shaken up a little due to various factors including a last-minute venue change, so space is limited. If you're really interested, drop me a message on XMPP ('me' @ 'matthewwild.co.uk') and we'll see what we can do.
Otherwise, come find us at the realtime lounge stand at FOSDEM and we'll happily answer any questions you have about XMPP ?
