as i understand it i'm too late for the current wcs version, but i figured i'd put this out there anyway, for anyone who might be interested: we should be able to restrict block's and replace's to certain users. for example, for km's server, figure something like NoBlockReplace= to let you set an access that is exempt from the following Block= and Replace= lines. examples of this line in use:
// these apply to everyone
// only admins can post web sites
// emulate that "capital letters permission" some servers have - we'll use ! for that
// other uses?
