I don't mean this in a bad way, but I don't think that the issue is with the chat system so much as this web site itself.

From what I have noticed, it is likely that the web layout of PC is a bit dated, which would in turn, make it more difficult to integrate a newer chat engine into it without making the whole website seem rather clunky.

Don't get me wrong, I am grateful for this site and I know that it can be hard to obtain the funding necessary to hire web developers as a non profit so I never complain about it; I just felt it relevant to point it out is all.

Perhaps, when I gain more experience as a web developer, I would be willing to help out any way that I can.
