Simple message board, has 2 levels catalog's structure. Allows to add/edit/find/show ad with text and attached files. Allows to subscribe to specified categories for immediately notification about new ads. I created it just for portfolio and shy to show it now because there is really poor functionality and design... But it works extremely fast. There used stored procedures for all database operations.

Used technologies: ASP.NET, MS SQL, T-SQL, stored procedures.
