[keycloak-user] Poll - should we have both a mailing list and a forum, or only one?

We recently introduced a new Discourse forum as a place to ask for help in the community. We believe a forum is better suited than a mailing list as it will create a great resource of knowledge, while the mailing list is very hard to search. The plan was to continue with keycloak-user(a)lists.jboss.org at least for a while to then revisit if we should drop a mailing list completely. However, due to a lot of technical difficulties with keycloak-user(a)lists.jboss.org (bouncing emails and users being unsubscribed) we have decided to move away from lists.jboss.org completely. Question now is should we only have the Discourse forum or should we also have a Google Groups mailing list? Downside of having both is that the community will be fragmented and there is a good risk that with multiple places to ask questions there are less people listening and ready to reply. So we'd like to ask the community what you think? Please fill in the poll at https://forms.gle/3URYHPU2wYToJcGh8 and let us know your opinion!
