Awesome! Thanks.
Yeah, that first-tag rule for forums is tricky. I'm not sure if you actually should bend that rule.
However, I would like it if the topic URLs (like https://beta.chainbb.com/topic/steem-standards) show all posts that include that tag like steemit.com does (although steemit.com also seems to purge old posts, which was why I linked the hashtag to ChainBB in the first place). The forum URLs (like https://beta.chainbb.com/forum/steem-standards) could continue being limited to posts that use one of the appropriate tags as the first tag.
