Maybe we can made it more like a meet then or something. I mean like, we meet and walk around in the room talk with this and that person. (Hmm don’t know, I felt maybe so we could come more into conversation with each other.)
I was at a polyglot meet-up in Zürich and there we made it like this, that we wrote down the languages we can and then we talked to each other, but mother tongue and English wasn’t allowed. (Oh maybe we could make something like that too. I’m not sure if we should do that all the time, maybe a part of it. Don’t know, if people would like to do that.)
Anyway I think you should choose 3 hours or so, for your meet-up. (I don’t know how long it went, after I was gone)
