[Zope] Odd wiki subscription behavior

I'm getting wiki emails from pages that I have absolutely no connection or subscription to: the two most recent were http://www.zope.org/Members/jeremy/CurrentAndFutureProjects/PerformanceMeasu rements and http://www.zope.org/Members/jeremy/CurrentAndFutureProjects/FastGlobals and I've gotten them over the past couple of days from some other projects too. Is this a "Zope bug" for the collector, or what? As in, how should I report this? Thanks Gary
