GotAnswers was heavily updated yesterday from Drupal version 5.x to Drupal version 6.x
After long updating times and lot of sweat I manage to update this site to the newer version of Drupal.
The most usefull information was a file called upgrade.txt inside of each module archive. Following their instructions I updated most of my old version 5 modules to version 6.
Before starting your updating your own site please read carefully the following guide http://drupal.org/upgrade/
Now I have to embellish my theme a little because now it looks pretty simple and clean.
