We are using static Drupal menu module + taxonomies terms. - When user is logged in we want to show Logout and My Profile links in the header section. - Weather block must have search box for user to select this city for the weather display and save into his account and cookie. - Grid view for Phone directory and website directory. We want to show some kind of grid with filterable countries. We also want to introduce categories or grouping of entries such as Hospitals, Entertainments, Ministries etc. Change emergency contact numbers to Important phone numbers. - Stock widget (may be in future). We want exactly the same stock widget as [login to view URL] and data should be coming from third party services for this. With Middle East section as well. - Ability to login via Facebook, Twitter, Google+, LinkedIn and Drupal. We want user to login via their above social networks. We want to store this user to system as well for demographic data purposes. - Ability to comment via Facebook, Twitter, Google+, LinkedIn and Drupal. We want to mix Drupal and above social networks comment system in the something like Disqus plugin. - Ability to share news on Facebook, Twitter, Google+ and LinkedIn. - Ability to auto post news on Facebook, Twitter, Google+ and LinkedIn pages (not news feed / user wall) to official account's pages. - Add currency converter to the sidebar as per previous website (WordPress) widget. - All the above features to website must be responsive and much be working on all modern browsers including desktop and mobile browsers. We are using media queries in CSS to handle this. Sincerely, Karim
