As of yesterday can actually go to beta.peakd.com and see how we are looking at doing the proffered topic list on account metadata (community settings option)... it will be easy to transfer the info to hivemind.
But I'll cc @asgarth and see what he thinks
And as I played with this list yesterday with one of my communities I actually changed the list a bunch of times but maybe once I get it set then I would rarely change it.
