Some BUGs are theme related. Some BUGs form within residents' associations and among users of certain streets. Some BUGs are big and electronically connected. The CIBC BUG has over 120 members who communicate by office e-mail. And there are all sizes and purposes in between.
Some BUGs keep on ticking, acting, and dialoguing.
Others form for one specific purpose, accomplish it, then disband or connect with another BUG or project. Talk to them about your idea to form a BUG and how it might benefit them. A survey also works, especially if it feeds into people's fantasies like secure parking or hot showers, and offers some hope of doing something about it. You can show a video or do something that competes with the local cafe's lunch special. For that matter, have it at the local cafe that's having the lunch special.
