I've been considering building one photo SNS site (similar to Flickr) and one wiki site in Drupal in recent days. Since I am not an expert, I found it a big project to build an SNS-based site with Drupal as I have to manage every small module.
Then I luckily found that Commons distribution began to support Drupal 7 (3.0 beta1). It's very exciting as it may save me a lots of time. However, I am not sure if the included modules can satisfy all my demand and surely in the future I have to add some feature to the sites.
So, how to learn Commons?
Say, about the theme customizing, module integration & compatibiliy, are they the same as official Drupal core? Maybe in other words is that, is it recommended for non-programmer to customize an SNS site with Commons?
I also find that it is recommended that server has 2gb memory and at least 1gb. It shocks me a little. Is the reqirement of 2gb memory quite common in Drupal? I am afraid I have to upgrade the VPS in that case ( >﹏<。) my current one only have 512mb...
The reply will be appreciated
