Trooper777123, the new message walls are likely to remain very Discussions-like. On the legacy platform, article comments, blog comments, and message walls use the same backend as Forum. On UCP wikis, they use the same backend as Discussions (Forum's replacement).

I have talked with the creator of RailWAM and they said they are working on a completely new version of the script. I am guessing they aren't going to bother updated the current version given that they are planning on completely replacing it anyways. You can see their statement at the end of this section on the script's talk page.
