Dupal 7: Improve a forum with functions, design and rules

We are currently running a Drupal 7.6 webpage with quite a number of users. A forum was migrated from phpBB to the Drupal forum module. There are only very basic design elements. There are currently no options for registered users to change any settings of the forum (e.g. notifications, show latest posts, sort the table, ... etc.) The tables show no date The sidebar with "latest" posts, topics or replies is almost not functioning and functional In the "my account" area of the user, the is no "my postings" or alike. Hence, we need a fresh and detailed design with nice features and functions. E.g. users should be able to configure the "notification mails" to being sent to their mail a) never, b) every week or c) at every single reply to their postings. Please provide any suggestions to how you would develop such ... We need a good communication and documentation for this. Also, professional functionality and administration on the backend for the webadmins should also be given. All contents should be e.g. be visible in the "rules", etc. I am happy to receive your application. Please provide information on when you can start, which components for the above work you suggest. Thank you for your application. Sascha
