Just a couple of thoughts...
If this is primarily a hand-tool activity the first meeting and slide show could be held as part of a Hand Tool SIG monthly meeting or Hand Tool Mentoring session. This might also get some more interest from other folks who might not use the forum. And from there we could find out how to hold future sessions.
Hand Tool SIG meetings are the last Thursdays of the month at 6pm it looks like, and the Hand Tool Mentoring studio sessions look to be on first Sundays at 1pm. If that works time-wise for people...
I'm also open to other ideas. And if future sessions would require power tool use, we can ask around to see who's in charge of adding additional sessions to the Studio calendar.
