I would second the not needing to give gold unless you want to work out a level of donation for star. My guild is run by our vice and he keeps track of the donations and increases levels based on that. We also had to put in place some guidelines for staying active. I think we ended up agreeing that if regular guild members didn't log in for 1 week and star for 2 weeks then they would be removed unless prior notice was given. Remember you will not be able to remove members during the Guild War so if you have folks who haven't logged in for 2 weeks they probably won't be participating in the war.
Good luck.
