I'm not entirely sure many people know about this, but there's a really nice BBCode guide here that showcases a bunch of tags that most people don't know about but could probably use at some point.

However, it is not conclusive by any means, most notably missing the [hr] and [youtube] tags- I'm not sure if there are any others that are accessible to normal members, and it would be nice to have these documented somewhere (preferably that page). I recall something about a [center] tag, too.

I... I’m ashamed to admit that I had no idea a page like that existed.

(the above is a test)

Edit: what is the point of the md5 tag? You can just quote the post to see the original message so I definitely wouldn't use it to hash my super secret passwords.

haha yeah... totally wouldn't use it to hash super secret things... haha 756081ae62edc9aa3f35bf2fe1e03ce0

I was about to mention HR and Center, my extension adds these, but I had completely forgotten about rainbow and sub/sup! I'll add them when I have a minute
Also is nobody going to mention that whoever added the Youtube button forgot to add the helpline
While I'm rambling about my userstyle, I added a color picker yesterday to allow selecting any color rather than just the basic default colors.

I'm going to bump this a bit, does cemetech add any BBCode tags that aren't in PHPBB normally?

I'm not sure what constitutes as "normally" but I know that mono is one that hasn't been posted in this topic. Wish the font size was a few points larger, I usually couple it with a font size 14 so it matches the height of the post font.

ninja edit: jk, I see mr womp womp has mono in his post.

I used mono in my initial post in this thread- it is incredibly useful for inline code blocks :)
