I can chime in on this one, it's actually a TON of work. Hope I'm not stepping on any judge's toes here, but since I'm staff and a project director/coordinator/assistant multiple times over, I think I can speak to this a bit.
Once all of the music for a project is completed, the whole album needs to go through the whole evaluation phase first, where it's basically looked at by a panel of staff to see if it's up to the OCR quality bar. Nothing really can move forward officially without passing eval. Also, staff needs to ensure that every artist on the album contributes a content policy agreement or else their songs can't be released on the album.
Once it's approved, some things involved in the release process include creating a fully-functional website with mirrors and a torrent for all artwork and music. The music all needs to be tagged and properly encoded to Larry's stringent standards in FLAC and MP3 formats. This is super in-depth.
Someone also needs to create an associated Facebook page for everybody to like. There's also the trailer and, eventually, uploading all of the individual tracks to Youtube and sometimes other sites like last.fm.
Somebody's also got to draft up a press release as well as arranging any promotional pimpage to other websites as far as interviews or pre-release reviews go.
Also, prepping any mixflood posts to accompany the album launch must be done, which entails a writeup by djp and separate OCR-format tagging for each song.
All of this needs to be pretty tightly coordinated on release day to make sure everything goes smoothly, i.e. the torrent is properly seeded, there's no typos on any of the release materials, tags, or the website, and that all of the songs are properly encoded and ready to be unleashed on the world.
There's probably more that I'm forgetting but that's just a sampling of all the stuff that needs to happen for an album to release. It's a huge amount of effort; I think a lot of folks start up projects assuming that it's just a matter of finding some quality remixers and getting a tracklist down, but it goes beyond that. Bottom line is, if you're not willing to be an integral part in making a lot of this happen, don't start a project in the first place. Getting claims and nice-sounding songs is often the easy part, but all of the non-music stuff really piles up. Staff will usually do as much as possible to help facilitate this but it requires commitment and effort from the director first and foremost to get there. This goes especially for big projects, as I'm finding out myself while tackling administrative/last-leg work for DKC3 and Maverick Rising at the same time It's totally doable and actually quite a bit of fun at times, but I don't think a lot of people are really aware of the time investment and effort required to do it right.
Hope that answers your question to some extent!
