I have just converted my website for IT support in the French Alps over to Drupal from Wordpress. I have created a new design for it at the same time.
I needed a bilingual site and the current multilingual feature set of D6 is not strong enough so I had to make the site in D5 using the i18n module. Another module that I consider critical that is not yet available for D6 was the XML sitemap module.
Other modules used were FCK Editor, Google Analytics, Meta Tags, Pathauto, Poormanscron, Token, Update status, Webform and Tagadelic. Notable quite a few of these also only exist in beta or release candidate for for D6 so pusing the choice towards staying with D5 for now.
I would be happy to hear any comments on the site.
Cheers
Phil Ingle
