Users can create new accounts for issue tracking, either locally or with Discord or GitHub. Those who do not want to create an account can send me an email (ian at this domain) with the issue details and I will create an issue on the tracker.
This is NOT a public Git repository service, and users cannot create repositories by default. Forks can be created for pull requests. Although this is primarily for my personal projects, some users may be allowed to host their projects here if they don't want to host them anywhere else.
