Knowing my interest for group collaboration tools, Sylvain recently pointed me to OpenGroupware.org.

After studying their docs I'm very impressed by the software - it seems like it would cover most non-code project management needs and could nicely complement my usual set of tools.

OpenGroupware also provides an XML-RPC interface (so they say - I haven't tested anything), which could be very useful in integrating such a tool with custom workflow or editing tools.

Thanks Sylvain! I'll keep this in mind.
