Hey world, It's an Arcane fan

Hey! I love watching Arcane and ive probably watched it twice already! I'm new to this site, but definitely not new to roleplaying in general. It would be nice to get some people to roleplay with! I'm also a bit confused by the way coding works on this site! I know HTML and CSS but when I type up code or wrap it in a [DOHTML] tag as I would on other forum sites i have visited before. I'm not sure if there is a different tag for it, but if someone could let me know how people deocrate the fancyposts that would help a lot
