Is there a sandbox area for fiddling with this implementation of BBCode/ PHPBB ?
I'm toying with the "color" tag and wanted to check and post a HOWTO, but I don't see a sandbox.
HOWTO : text colour
The "color" tag is A ColourValue may be either an RGB hextet (#123456 for digits in 0..F) or a text string. A partial list of recognised strings is below, with their equivalent hextets.

Blue, 0000FF
Brown, A52A2A
Cyan, 00FFFF
Darkblue, 00008B

If there's a snadbox, shouldn't there be a "HOWTO" thread too. Hopefully after each guide has been debugged.

I'm going to try a revision :

HOWTO : text colour
The tag is (open.sq.bracket)color=ColourValue(close.sq.bracket)Text(open.sq.bracket)/color(close.sq.bracket
A partial list of colours recognised is below. You can also directly specify an RGB hextet with #123456 in place of a ColourValue text string.
[blah blah, snipped)

Would the CODE tag allow me to write (open.sq.braces) without triggering the BBCode background? Yes, it does.
