Converting to Drupal

I have a simple use case that I'm sure thousands of other Drupal users share. I have a simple site and I'd like to enable comments, but I don't want to have to deal with a lot of spam. My ideal solution is to let people log in with OpenID and then present a captcha before they can post a comment. I thought the point of OpenID was SINGLE server registration, but this is not how Drupal OpenID is implemented. In order to log in with OpenID on my Drupal 6 site, users are still required to create a Drupal registration.

so where exactly does drupal add value over wordpress? I use wordpress for many of my smaller projects as a CMS. Why should I start using Drupal?

hi i'm currently using WP 2.5.1
what version of drupal that would work best for importing my posts , comments ??

thanks

Where can I find a gallery of websites created using Drupal, alongside the code used, so I can see how Drupal works in action?

Thanks,

Mark

Need to do a find and replace of text through the entire site. Is there a module that can do this or do I need to go into MySQL? phpmyadmin looks promising, but all I could find was a tutorial on changing one table at a time. Need to search and replace entire database.

Newbie to databases, so the simpler the better. Exported a Filemaker database and imported it into Drupal with Node Import module. Had a bunch of problems with special characters, so I did a find and replace in Filemaker (very easy) to removed the offending text. Now I need to replace the text...

Thanks!

I am totally stuck on this one. I was reading the info here: http://drupal.org/node/38960

But nothing in this article seems to be helping me. My old site had all page requests coming in as

/index.php?page=page_requested

I need to rewrite that so that the user will now hit the new pages using clean URL's.
