Simple message board with 2 levels structure (category/subcategory/items). Allows to add/edit/find/show ads. Allows to subscribe to updates in the specified categories for immediate notification about new ads. It has been created just for portfolio and I shy to show it due to poor functionality and design :-) But it works extremely fast instead. Stored procedures used for all database operations.

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