Here "trusted" users can upload patches and other files related to the GS-10, and anyone can download these files.
To become a "trusted" user, all you have to do is wait a while after your registration: when I'm satisfied that you're not a bot or otherwise evil, I will make you a trusted user. This should usually occur within a day after registration. If you still can't upload files after about three days, you can drop me a message via the contact form to convince me you're not a bot.
I've copied a lot of files from the Yahoo GS-10 group, mainly patch collections.
Many of these were collected and uploaded there by me anyway. In particular, I'm responsible for all the conversions from the GT-3 and GT-6, except those in the Lidman collection.
