Requirements:

* Using Elgg (http://elgg.org/) framework and do customization 
* Must be experienced in PHP/Elgg/AJAX/JQuery/MySQL
* Please do not apply if you do not have experience with Elgg customization

User Scenario:

1. User comes to the website and login using LinkedIn.
2. He has two options: 
a. join a group and 
b. ask a question.

2a. When joining the group, he can i) ask questions, ii) view all members in groups.
2b. When asking a question, the user will have to select a group where he belongs to.

I have already setup Elgg and the plugins that support most of the features, but we need the following customization:
1. Save more LinkedIn fields into the database, and list that in User profile
2. Email subscriptions / notifications to groups / questions
3. All the questions will need to be coming from a group
4. Some front end UI work.
