You have the date and this is a perfect opportunity to get some publicity. If you live in Tortosa or the surrounding area I would suggest you consider getting together outside the venue of this meeting with some placards to state your case. Do what you can to get some attention and publicity but make sure it is entirely amicable and peaceful. Don't let this opportunity pass you by. I'm sure the Catalunya Chronicle would be there to interview you about your predicament, and perhaps some Catalan papers too!
