It might be a good idea for you to organise some meets and let everyone know when they're going to be.
You might get a regular group together, although a lot of the members go to meets in a few different areas, there's always the issue of finding a place that has the facilities that bushcrafters find desirable. You'll need to find a place that's happy for you to pay when you all arrive, although you'll find it hard to let them know how many to expect as there's always a few that don't turn up or turn up unexpectedly...Umm, there's loads of considerations really when you start getting a group together, when it comes to a small group of 3/4 people it's quite easy, start getting into the 10 plus and it becomes a lot more complex to pull together.
I suppose the easiest way is for you to just say that you'll be somewhere at a certain time on a certain day and anyone is invited, prepare to be alone sometimes as well as surrounded by people at others.
