How to register an account on GitLab. Due to spam, new accounts are locked until approved by an admin or the approver bot.

Only if you are WMF staff: Create your GitLab account, have "Wmf" group membership in IDM, link your Developer account ("LDAP") to your Phabricator account, and get automatically approved.
