Thread:Project:Support desk/wgUsersNotifiedOnAllChanges: Send less mails!?

As sysop I use wgUsersNotifiedOnAllChanges to get notifications for all edits on my wikis. Sometimes I get really spammed by those mails. Is there a way to get less mails, say only 1 mail (per hour for example) if a user has changed one certain page 20 times in a row?

Thanks!
