Hi,
I have a sense you don't visit the Event's board. If you want a supper club, why not suggest it as an event?
I find the meetup seems to work on a different dynamic. The official hosts pay a fee to meetup, then charge a small fee to reimburse themselves from participants. I can see where it not only covers the hosts expenses, it might generate a profit.
On LTH, people meeting in a restaurant will split the bill amongst all participants. At the one meetup dinner I went to, everyone was expected to figure out their portion as well as pay the host $2 each.
There are three LTH food exchanges: a dessert themed, an omnivore and the other vegetarian, who meet once a month, though omnivore is suspended for the summer.
Once there was a wine-pairing meal, where the host matched wines to suggested recipes. It was a lot of fun.
I can easily envision a rotating dinner group, too. It probably happens informally anyway when one person or another has a party, then everyone brings something to share.
Regards,
