MyBB Remote DB Connect, Auto-Login and Restrictions

Hello, I have 2 websites; one is our main site and the other is a new MyBB forum site. I need to have the following work done: 1. Remote connect the forum to the site database: If there is another option that is easy I am open to that. However I have two user types: Clients and Models. Ideally I need the users to automatically be logged into the forum (via session) and based on their user type. Therefore if they are logged into the main site and go to the forum they will automatically be logged in. 2. I need the forum homepage to be the main forum. Everything will be a single on-going post thread, so I just want people to automatically go to the thread. This should be easy but when I change the home page in config it messes up the design. 3. Clients order services from Models. Those are the two user types. So I want to apply access restrictions based on recent orders and sales. For example if a client has not purchased anything on our main site within 15 days, or a model has not sold anything within 15 days I need to redirect the user to a custom URL (I can make the redirect pages). Something like: $sql = "SELECT * FROM `client_orders` WHERE `model_id` = {$user_id} and created > NOW() - INTERVAL 15 DAY ORDER BY `client_orders`.`id` DESC"; else $sql = "SELECT * FROM `client_orders` WHERE `client_id` = {$user_id} and created > NOW() - INTERVAL 15 DAY ORDER BY `client_orders`.`id` DESC"; I can provide DB access FTP/cPanel access and help you find files to make the process easier. *BTW this is for an adult entertainment service. Please be aware of this before bidding. You will not have to deal with any of the content, just the files. Thank you
