I wrote the bylaws for the biker group I pack with. I could use my experience there to take input from the LUG. Then generate a charter and code of conduct for the LUG
However, that may be a bit extreme, as I don't foresee the LUG members prone to tossing tables and stomping some dude for talking trash about his 'nix machine.
As for electing officials, I we get some one to volunteer and do an election by email. Candidates can nominate themselves via the newsletter. On a determined week all who receive the newsletter can vote by email. the volunteer takes tally and informs the group who won by the email.. Validation can be done by an independent reviewer, the process would to have another volunteer, examine the tally and have each voting member send their vote to him as well.
