Drupal does not support lighttpd as a server for deployement. And appart form the problems you may have with .htaccess files not working, there is also another minor bug: https detection in drupal is done with the $_SERVER['HTTPS'] variable, which is not available when running PHP in CGI mode with lighttpd. The result is that you will be moved to http after logging in via https, which is not what you want. So a quick fix is in order.
I you want to post nice gadgets or things like Google AdSense code in a block in Drupal, you will find that the default Full HTML input format does not work. This is because the default Full HTML will still do some checking to make sure you don't screw up and inserts linebreaks.
So, to create a completely Full HTML input format is the best way to go. Here is how.
Yeah, my first www.drupal.org posting, a full module in a snippet. The code defines a module that exposes a block and a trigger. The trigger will be fired when the special trigger block is shown. The trigger block itself only contains HTML comments.
