[quote=@Mahz]Once I extend the bbcode as I specified above, I'd like to revisit the idea of letting people optionally write html.

There isn't much difference between html and bbcode except that bbcode is obscure, ad hoc, with no tooling, and annoying to parse. Do you know how many times I've started writing my own bbcode parser over the years?

They're almost equally bad to write by hand. :lol And my job is no different between them: I have to somehow map bbcode to html, and most bbcode maps 1:1 with html anyways. Like [code][list][/code] and [code][*][/code] are just [code]<ul>[/code] and [code]<li>[/code]. So what's even the point?

If I were to do this, I would let you choose whether your post is in "bbcode" vs "html" mode so that it doesn't touch the existing bbcode system.
