Chat is the cause of most of the problems related to the server. It is a super-intensive resource hog and everything we've tried to help with it has not helped. We've brought in outside consultants. Nothing has helped. We've spent considerable time and resources troubleshooting it, to no avail.

In short, we're left with very few good options. As usual, there are no really good chat products available that don't have similar problems (or other issues). Chat needs to work as well on mobile as it does on the forums, and integrate with our existing user database. This eliminates many products on the market.
