Congratulations on taking the plunge and writing an open source
plug-in for the Eclipse platform.
SourceForge.net can provide a good home your plug-in, but

This article is an introduction to SourceForge for the Eclipse
developer. You will learn the features available to the
SourceForge.net open source developer community and be guided
through the process, from creating a SourceForge project to
hosting your Eclipse Update site.
