Honestly,

The lack of explanation for what happened: "we're working on it" only works for a few days, not months and then for it to stop the day it started working again, is inexcusable.

This is not rocket science. This is a service run off a commercially available BBS system and I partake in many other sites where messages never stopped working. Internet Brands has some work to do - either with the quality of their staff or their investment in resources to make things work. Either way, this is a big FAIL.
