The banglist is still available at the link: http://www.freerepublic.com/focus/keyword?k=banglist
If you're referring to the fact that the old search facility is missing, which enabled searched by "keyword" and "poster", yeah, that's a bummer. I used them a lot, and I don't see any replacement anywhere, so that's a major decrease in functionality for me.
On at least the News / Activism page, when I hover my mouse cursor over the new search box and left-click, a yellow box magically appears that includes a dropdown menu that allows selecting between keyword, users, titles and Yahoo for your search parameters. It does this for me on my Win XP Pro system with IE as well as Opera; I haven't tested with other browsers. I'm assuming that it's a Flash thing, so if people don't have that installed it may not appear. I'm no programmer so don't take my word on that aspect of things though.
