<snip> The version is very relative. Drupal 7 does not have as many modules or templates as drupal 6.20. I like many things about drupal 7, but i have not yet changed ver 6. </snip>
I was using Drupal 7 beta 3 because drupal 7.2 was not around, it seemed to do what was needed. Drupal 7.2 is still on the edge as far as modules and other niceties but I reckon our needs are low at the moment and by the time we are ready to release the sites there will likely be more drupal modules.
I really do not want the hassle of trying to change the database over from 6 to 7 some months down the track as it will have fairly redundant data, I'd rather start with the databases we will be using for the next 2-3 years, one less hassle. Roger
