An online forum I frequent uses XenForo software which is pretty much the latest-and-greatest version of the old vBulletin software that CAF used to use.
I was astounded that CAF did not choose XenForo. However since I have learned how to use this new CAF software from Discourse, I must say that the XenForo/vBulletin software is very antiquated and underpowered in comparison.
Not including the IGNORE key was a grave mistake by Discourse, but otherwise this new software is light years ahead of XenForo/vBulletin.
Hang in there! It takes less than a month to come up to speed with the Discourse software.
