Chuck Burgess has a quick post pointing out the next "PEAR triage days":

PEAR's next Bug Triage days are this weekend: Saturday 4 PM - 9 PM UTC and Sunday 4 PM - 10 PM UTC.

You can find the schedule and more information about joining in at this page on the PEAR wiki. You can find others working on the triage on the EFNet's IRC network in the #pear-bugs channel.
