I'm a developer for a trivia game website called http://www.BrainDash.com/, and I've been tasked with integrating Elgg with our site, so that users get consider both sites to be joined as one and the same. 

As part of that task, I've got to:-

• Integrate user registration
  
• Integrate user login
• Integrate the BrainDash.com theme
• Integrate profile information (ie show game scores and evens in elgg)

As part of these tasks, I hope to document how I go for the good of the community, and as a result of integrating BrainDash.com, we hope to be able to offer the services of BrainDash.com for integration of other peoples sites.
