I don't think the old site is accessible. Whether old content can still be brought over by the developers, I don' know.
I really struggled with the new site. However, I've done my own styling overrides to make it work how I want it to - or at least much closer to how I want it to within the limits of being able to override the site's structure and styling. I'm quite happy with it now. The overrides I made only work in FireFox but there may be ways of adapting what I've done to make it work in other browsers. For info see here....

I haven't bothered changing the pages I use infrequently and there are some 'bugs' in what I've done - eg the popup member info overlays the Like, Reply (etc) buttons for short posts so I have to click into the post's test then tab to the link and hit enter.
As with the new site - you may need to hit the link - then hit the link again once your browser has cached all the images. I find that the # bit of the links which goes to specific posts go there, but then images further up the thread are read and pushes the page down so its no longer where you were directed - if you then load it again with the images cached - it goes to the right spot.
