Indexator.NET is an application written in C# that is able to index directories and store information about the files found in a MySQL database, associating it with labels (so it can be used as a CD cataloguer). The information can be consulted in several ways: a console client, a graphical client (GTK#), asp.net Web, an asp.net service, or using remoting. It has two main objectives: to be used as a CD-ROM cataloguer, and to be used as a way to explain the possibities of Mono (and .NET) in educational environments.

Openmailadmin is a little administration interface to every complete IMAP mail server daemon. It supports every feature IMAP provides, and fits in most MTA configurations. A key feature is the non-standard, generic administration hierarchy which not only seperates "normal users" from "administrators", but enables the mailserver-master to create instances between them. You will be able to let other users create their own sub-users and thus either share a single mail server between different organizations or project your company's employee structure. It excels with features such as regex addresses and folder ACL management.
