I run a non profit based .net user group called DevEvening (http://www.devevening.co.uk) and am always looking to improve it.
I wondered what people liked and disliked about user groups and what could persuade people to attend who did not already?
Since your using this site I guess you have some outside of work interest in development - do you attend user groups?
I have been to a number of events and different user groups and although the quality of presentations etc have been mixed I find it is always interesting and useful talking to other developers.
