I can't speak for every remixer, but I tried my best to produce WIPs for a wide array of projects. If people are interested in a project, they will probably help it. You can't really "force" people to help a project they're not necessarily interested in. Having "too many projects" is just a way to give people more variety, and a chance to work on something that they love. If they end up loving 5+ projects, then that's fine.
Granted, my status is probably a lot different than most remixers. I can put hours and hours into remixing every day, and I usually finish something I'm focusing on within a day or two. But I still think variety is a great thing, even if people are very busy. If they're not making progress in a project, they can step down, and someone else who is interested can take their place.
I could go on, about how people should be more accepting of new musicians coming to OCR, and things such as that, but I know nobody wants to hear it. Still, there's hundreds... thousands... of bands and musicians out there that might want to take a crack at a song or two. Just because they're not posted here, or don't have a rep, doesn't mean they shouldn't be able to audition for any project they want.
As for removing claims for multiple-track people... Sorry about that. Seemed like a good way to proceed with things, and it seems to have raised the productivity of people who are devoted to the music. This is also a call to anyone who hasn't claimed yet, steal the track you want now before it's too late.
@Josh Whelchel: You claimed something else before Immoral Melody, and I knew your main interest was in your initial selection. I hope I didn't cross any lines by personally choosing which track you have claimed. If you wish to change your selection, you are more than welcome to do so.
Thanks.
