Hello,
Right now we in the Bookshelf Project are preparing a number of booklets and brochures and you are welcome to participate in the work. We look forward to any comments you may have to any of our deliverables: http://outreach.wikimedia.org/wiki/Bookshelf_Project#Deliverables
One of the easiest pages to begin with is the one called Ten reasons to contribute to Wikipedia ( http://outreach.wikimedia.org/wiki/Ten_reasons_to_contribute_to_Wikipedia_%2...). The people who are producing these materials have their reasons, but we would like a broader sample of reasons. We would, in short, like to hear your reason. So think for a minute about why you contribute to Wikipedia and add your reasons to the Outreach wiki. Don't feel you have to stop when and if we should hit ten. We can always sort out those reasons later.
The deadline for the Bookshelf deliverables is pretty short, since the entire project ends (?) at the end of September, so please be quick.
Best wishes,
Lennart
