There should be an admin flag for all ksf members to determine who's in the clan or not. This should probably not have any actuall admin powers, but should show up when you type /who. This way, I wouldn't be tempted to ban random people I don't know with the ksf tag on. It should be given out as soon as somebody is allowed to join so that other clan members can confirm their enrolment. Many times have I seen people I never saw before with the tag on. When asking them why they have it, they say so-and-so let them in. Kinda hard to confirm it when so-and-so isn't online.
