Group members are strongly advised to create an account for the group and upload torrents when logged in. This allows you to manage your own torrents, provide a group listing on the site, and provide group-specific RSS feeds to your users. There is no limitation as to how many accounts you may use or share with others. Create and share a new account for each group you are uploading for if you so wish.
