Due to an influx of spam, we have had to temporarily disable account registrations. Please write an email to accountsupport@archlinux.org, with your desired username, if you want to get access. Sorry for the inconvenience.
Merge requests and Issues are disabled on Packages for non Arch Linux staff - we plan to open these to all registered Gitlab users in the foreseeable future.
