To make URD bigger & better :)

• Let us know of bugs and problems, so we can fix them
• Tell us which feature(s) you're missing
• Recommend URD to people who might be interested
• Write about URD on blogs & forums
• Create new language packs
• Create new themes
  

The more people that use it, the more feedback we get, the better we can make URD.
Plus, with the community-based set information, the more people that use URD, the better the set information becomes :)

And if someone were to make a good comparison of different usenet clients (including URD :P), we gain notability that we can use to clean up our Wikipedia page :)

On a side note, 0.5.5 is almost done. We just need to fix a few more bugs, but you can expect a release in the next few days.
