To stem the tide of spam accounts, we have started, as per v0.15.1, to request new sign ups to very briefly mention why they want to join our instance (Baraza). We know this is not ideal, and we hope to keep improving the sign up process, and likely remove this application step. If you do not get the registration email, check spam/junk folder for confirmation.
So, why do you want to join Baraza? If you came with an invite code, paste it here.
