i just had someone on /notify but didn't want them on after a certian time cuz i have a sound when they log on. I could just as easily added /notify -r nickname in an on start event or just a timer to notify -r them (cuz i'd forget to do it manually) but same could be said about ban -u and ignore -u.
Since i don't think its been mentioned before theres obviously not a great deal of call for it, which was why i asked if others thought it might be useful, rather than just saying i think it should be added.
