Has the "Toggle Sidebar" option disappeared from the individual forums? I used to see it there, next to "Open Quick Navigation" right at the top of this (and every other) forum, but now it's gone. It's still on the home page, but clicking it only affects the home page--it doesn't carry over to the individual forums. It's a shame, because in the past, turning off the sidebar made the forums load much faster.
Generally speaking, the site is so bogged down with I don't know what--ads and useless banners/columns/junk, maybe?--that it's super sluggish and often completely unresponsive. I usually can't finish scrolling through a single page without everything slowing to a crawl and having to refresh the page. Posting is a chore, as the site often locks up while I'm in the middle of typing a post. Overall, it's a pretty frustrating experience. I've tried using different browsers with all extensions turned off, and it doesn't make any difference. Surprisingly, viewing the site on my mobile devices offers the quickest experience.
Chances are we've seen most of the problems already but please do send in any feedback. You never know and good ideas are good ideas.
