Nothing to lose sleep over, but..
In short, the problem is that people appear to stay online in the chat list, even when they are verifiably logged off, meaning that opening a chat with someone only seemingly online is futile.. unfortunately the chat window gives no indication as to the person's real login status. I think this is a critical bug in the chat.
Another, merely severe, issue, is the dropped lines - not infrequently, the recepient fails to receive a chat message, or vice versa. Again, with no indication that delivery failed.
Now, "severe" and "critical" are relative terms on a Saturday afternoon, and I do appreciate the fantastic, free, service that Glocals is :)

P.S.: Don't put a Facebook like-button in there, pls (a like-button sends a message to Facebook about which pages, you surf on.. each of them, if they have a like-button - regardless, whether you click it or not. Here's a counter-measure. Now, glocals is arguably benign, but it is still nothing of Facebook's business from my point of view.)
