Does anyone have an idea about the "Where"
I personally could participate everywhere in Germany and maybe in England. But the latter is significantly less likely.
Deciding on a format (i.e. length of time and approximate budget) would be a good start. Like, if we're meeting for a day somewhere in Germany, that probably works well for you, faust and silver, but it would be a long trip for such a short time for people like me.
If we're meeting for a long weekend (or possibly for a full week?) with boardgames and Mafia and stuff, then cost of accommodation starts to become the dominant factor, but if there are 8 or us or something, I expect we could find something decent for under 20 euros per person per night, if we're all happy self-catering and sharing a place. With budget flights or cheap advanced train fares, travel across Europe can often be pretty cheap.
The other option is to have someone to host it at their home. I have my house, but it's very small -- it's quite crowded even with just LL & Fargo staying at the moment (plus me and my lodger), and there's only really space for one more person if they're sharing my bedroom! I also definitely want to have a bed to sleep on, rather than just a floor or air mattress, in case I get back pain again.
What sort of things are the rest of you thinking of?
