We have a support category for the Italian Linux society association where users not registered can ask for help. Now is an email, so we have a group of volunteers doing it, but we want to move in the forum so also other people from the community can help with that and be transparent for it.
The registration is under the SSO in SAML integrate in discourse so the issue for us is that discourse don’t send any email to the staged user that created the thread when people reply to it.
There are a lot of people that prefer to send emails (this email exists since years and is public also for people outside the community) also without having an account, and we are allowing just in this category for this purpose and helping all the people doing the migration to the platform.
