Single sing on. Have a look at the option:
$Configuration['AUTHENTICATION_MODULE'] = 'People/People.Class.SingleSignOn.php';
in vanilla/conf/settings.php and appg/init_ajax.php which is where the default it. This tells vanilla which file to use to do authentication.

Then look at vanilla//library/People/People.Class.Authenticator.php which is the simple template. You can then copy this file to something else (those name goes into the option above) and edit that file to suite your needs.

Simple.

This issue is because of an unsafe use of ForceIncomingString() in the addon. Each
and every use of this function should be wrapped in htmlspecialchars() to avoid XSS
attacks.

Edit files the files default.php library/Function.TagThis.php and make change all
instances of ForceIncomingString([...]) to
htmlspecialchars(ForceIncomingString([...])) and the code should be safe.

Could you check issue #19 at http://code.google.com/p/lussumo-vanilla/issues/detail?id=19

Thanks.

Hey,

Do you have any idea how I could hack your addon (Panel Categories) to high light which category the user is currently viewing? ...

Yes, you would be able to. You have root access to your server, so you can host anything in there that you like. We do not get root access unless you give it to us.

You said you work with Bytemark; would I be able to host NZB files on the Bytemark servers? http://www.newsgroupdownloaders.com/nzbfile.html The NZB file is just an XML file, but it may reference locations on Usenet where copyrighted material may be.

On your Bushido theme screen shots, you have a calendar on the left hand side. Which addon is that?

Thanks.

Thanks. That was useful.

PS: I'm not including 'source' code because what I had to do in vBulletin to make it work will have zero relevance to doing it on Vanilla (and most of it is full of vB's arcane "template conditionals")

Just create a conditional that says "if they don't have an avatar here..." that does this:
http://en.gravatar.com/site/implement/php (and make a nice default avatar for the newbs) :)

Gravatar addon... Any chance you could bounce me some source code? I don't know php at all but can probably hack at it -- C, C++, Python, Ruby, Haskell, all those I know...
