The old version of the BYOND website had really nice support for use of a web browser's back button. The new site doesn't seem to have the same support.
What I mean by support is that on the old version of the site, whenever you used the back key, it would also act as a refresh key, so that any topics you looked at and just came back from, would be marked as read, counts updated, etc. ( I use the back key way to much to navigate).
I don't know much about how possible this is to implement with the new site, but it was a nice feature of the old one. Its something that I don't see on any other website.
