subscription emails

[upnorth]

wondering if someone might be able to help me with this.

Currently when a user subscribes to a forum they will get an email notice once a day indicating what new posts were made. I'm wondering exactly how this works? and whether I can change this task to run once a hr but reset itself.

Please see this link for info as I posted this question over at vBulletin.com and they pointed me here. http://www.vbulletin.com/forum/showthread.php?t=227314
