Sure: check out

I am going to post the flyer there tomorrow or tonight (need to change some minor things on it). The DJ Orestes from Havanna/Bern (an expat too) is going to be there.
I'd say anyone who is coming from your club only has to pay 5 fr instead of 15 (sorry that it is not totally free but I must pay the DJ, the flyer etc etc).
I have registered too by the way and will tell my friends at work about your club as we have been talking about an expat club for salsa people missing in ZH (no longer now :-) ).
