Last night (and a few others the past couple weeks) our groups decided to play hooky and go tack a dip in the Hudson (yuck). After a bit of downtime groups returned to the site.
We apologize for any inconvenience this may have caused you. We know how annoying this can be when you have events and news to post. This morning we nailed down and fixed the bug causing groups to not properly function.
Thanks for your patience and understanding. We will always do our best to keep features consistently up and running.
