Development of forum module for existing website

We want to add a forum section to our website. This module will be a customisation of one of the open system forum solutions: phpBB SMF You can choose which one to use, depending on which can be customised best to the design we will supply. This design will contain all standard features of forums. It will also feature an imported avatar (picture of the user) from their profile in the main part of the site. You will need: • Knowledge of at least one of these forum systems • Ability to theme the solution to be consistent with the rest of the site (we will supply design (colours etc) • Ability to provide single-sign in at point of entry to the main part of the site – which is developed in ASP.NET – without needing to log in again to the forum. • The developer can choose the specifics of the solution used but it is assumed that a cookie-based system will be best. • If so then this needs to be secured against replay attacks and should be secured with some kind of encryption or hashing technology. • It will be important NOT to use the ASP.NET session cookie.
