That's too bad about the notification capabilities. I looked in the settings, and I didn't see anything, so I assumed that was the case. But man, it's such a nice feature. That way you know instantly if someone replied to you or not - and it makes it so much easier to keep discussion flowing. However, I also understand this is an older board ... and I've just been spoiled with recent technology/shiny tools. lol.
An eventual upgrade?
If I'm reading this correctly, it probably takes care of the notifications issue (and so much more). And, really, gets you a huge upgrade overall, and therefore, likely a better, smoother experience. Also, if I'm reading this correctly, as people continue to upgrade browsers and whatnot, this older version might have some serious issues.
Just an FYI. I'm slacking a bit today and looking into random things. Figured I'd mention it!
