The Dutch website www.chivo.nl has been up and running voor 6 months now, but has some quircks, that require someone with more in-depth knowledge of Drupal to solve and maintain:
1. Seems to run out of memory for certain tasks (creating roles for example)
2. Some userlinks do not work
3. Forum refuses to install
Software: Drupal version 7.12
RAM: 32 Gb
When we can resolve these issues, more (challenging) projects lie ahead. I'm looking for long term maintenance and customization. That's the reasons why I also added PHP / AJAX and MySQL skills to the required list.
