I'd like to use a [username=] for a NPC (for example: [NPC]Nico) in my topic, but it seems impossible since it has brackets in the name. Even linking to their profile can't be done without posting the entire link. Does anyone know a way around this?

I only have a guess. When it last worked, you needed to put underscores in. So it'd be _NPC__Nico or maybe even [_npc__nico] if it's one of the weirc compound names the system seems to choke on.

However, I wasn't able to work it properly ever since they made their HAs all of one piece a while ago so this might not be possible anymore.

Yeah, I tried out what you suggested but it doesn't seem to be doable. Thank you for answering my question though. :3 I really appreciate it.
