The other important thing I should mention, is that
none of these commercial companies have ever paid a single cent to the Plucker project, in terms of time, dollars or other contributions that we have seen or measured (other than Palm hiring off one of the team for a small consulting effort).
If any of these companies are here, reading this, and have contributed back, please let us know, so we can publically recognize your contributions!
Of course, we would love to see more contributors and commercial supporters. We've asked dozens of times for help with various parts of the project (documentation, translators, website, sample documents, news articles, etc.) but nobody really seems to step up to volunteer, unless there is some sort of "reward" coming back their way. If they're not getting "paid" to help out in some way, they don't want to help at all.
Many people just don't understand Free Software (the kind with the capital "F", not the kind with the lowercase "f"), it seems.
In that context, there's a
great HOWTO on exactly that. Its worth a read for those who would like to contribute, but aren't exactly sure how.
