I'm ok with sharing what I have, but I believe it's in everyone's best interest if we each maintain our own libraries. There are plenty of free web hosts around and look at what happened each time there was a huge, centralized MML library. After each crash the music comunity in Mabi had to take months to recover. That was months of either random spam or no music at all for new players.
Sure, it weeded the garden and kept the less interested or the less talented from growing, but it stunted the bard community also. Those players could have eventually contributed, if they had had less dependance on central library sites.
That said, no I will not be hosting other people's MML on this site. It is only for what I have made or what I use. Think of it as a protfolio. You don't just walk up to your favorite artist and ask them to put your work in their portfolio.
Also, I will not be taking requests directly on this site. I play on several game-related forums and can easily be contacted on any of them.
I think I will be putting some of this on the main page, just to be clear with new visitors.
