Prontowiki is a small wiki engine written in C# using the .NET 2.0 framework, and relies on SQL server for data storage. It is quick and easy to use. The syntax is mostly an outgrowth from the wikiwikiweb syntax. Permissions are on a per-user basis, and user authentication is driven by the .NET membership classes. Image and file uploads are handles through the database. Custom tags can be created to achieve nearly any syntax desired that is not offered in the basic syntax.
