Hey People I'm doing some research around setting up a website. The site will allow people to sign-up, complete a profile and submit their blog(s) feed (RSS, Atom, XML) which will automatically syndicate it to their user profile and also the homepage. I know this sounds like every other bookmarking website out there but what I want to know is... are there any CMS, or "Out of the box" solutions that make setting up this kind of site easy? Thanks in advance guys and gals.
