For these people they may still be very valuable. Non-technical documentation, writing experiences or reviews for the Ubuntu magazine fullcircle, and just becoming more familiar with the Ubuntu system itself. Self-learning, with help from support on irc or forums if needed, will help you understand the system better. If you find out something useful that was not easy to find elsewhere then document it as others may be in the place without seeing answers.

Bug triaging and packaging help may be easy for a seasoned Linux person, but for a new user wanting to make their contibution, there are still ways to help.

I so want to join in but my enthusiasm can seem, as Jono put it in a videocast, like an idiot. No one wants to be an idiot but sometimes we do things without thinking it through.

Lets hope we can all start small and work our way through to being really useful instead of idiots!
