Treating parties differently based on how large they are doesn't seem very fair. I also agree with something Tsu said on Discord, that forums off the index aren't really seen and thus suffer in usage.

My honest opinion: some TSPers freaked out over TIL's private off-site forums and decided that all political party forums should be here. We have to live with that, now, even if the index gets bloated with a bunch of parties that only have 4 members each.

It doesn't make sense to me that we've made a cultural taboo that forces parties to get subforums here, but now we might be trying to decrease the visibility of those forums.
