Well, it's semi-public - read only except for registered users, and
it's only a week or so old, so we're still using the monobbok skin,
for example. I need to get this #if problem fixed so we can go on
to more aesthetic issues :-) and there's so much to get up to speed

There's a test page at
and the template it uses is at
{{#if: {{{x|}}}|yes|no}}
and Test renders as
{{#if: |yes|no}}
{{#if: xyzzy|yes|no}}

The only source code modification is to fix the bug in Language.php, line
1137, missing an "else" (there is an entry in bugzilla for this).

If you need an account to diagnose this, please let me know.
