Steve, anyone can host a GB and its up to them to keep things going, come up with the rules etc.
The thing about new members starting a GB isn’t simple a case of getting some creed. As I am sure you can appreciate, when ever you join any established group, it does take a little time to get yourself known. That as much down to the new member as it is down to how welcoming the group is, and I must say you are off to a good start. When it comes to hosting GB’s, its generally good advice to take part in a few before hosting one. I was a regular for about 2 years before hosting my first and some other, like wayne, took even longer.
It not only means you get a feel for how GB’s are run, but also get you known on the forum as someone who is committed, rather than someone who might start a build and then just vanish because they are bored with it.
If you do want to run this GB, might I suggest looking at what other GB’s are currently running, we have close to 30 at the moment, and consider if there is room for it currently or if maybe it could be fitted in in the future. You might want to start a feeler thread in which you can put the general rules, start and finish dates and so on. then you can see if there is enough interest. Some subjects are more popular than others.
That’s my 2 cents anyway.
I posted this last year to help new members many of whom were asking about GB’s. hopefully it will help get an idea of how they run.
