fixed account details like this website

If you look up this website (freelancer.com) when you scroll you see your account details is still there. I want similar in my classifieds website with account info so also amount of money in account dashboard with account links financial dashboard support, and a button post auction/classifieds, or select option to post either classifieds or auction Since we use geo classifieds script this must be created as add-on, otherwise it will get overwritten during upgrades of the script There is a nice wiki on the website for developers to build add-on [login to view URL]
