Modifications for Ruby project

There's open-source web-project created using Ruby framework Merb. The project is deployed on VPS-server with UBUNTU 11. Several modifications should be made to the project: 1. User interface modification: 1.1. Remove a link from homepage and user menu 1.2. Add 3 new items to user menu (these menu items are available to users with administrative rights. They should be available to users with general access rights as well) 1.3. Change page layout (there are 8 sections of data on the page. The order of these data sections should be changed) 1.4. Remove logo image from mainpage and put the logo image into the page header as per sample layout attached. 2. Bug fixing: 2.1. "Statement Invalid 500" error while new user registration and while accessing some pages 2.2. Error message while starting merb: "/var/lib/gems/1.8/gems/merb-core-1.1.3/lib/merb-core/dispatch/router/[login to view URL]: [BUG] Segmentation fault" 3. Email notifications for some project events 3.1. User registration confirmation 3.2. Message to the user with "Forgotten password" 3.3. Application to join a team: request itself, request accepted, request rejected 3.4. Invitation to a team: request itself, request accepted, request rejected These events do exist in the project and are handled accordingly.
