A few days ago I decided to go to http://jointhegame.kde.org/
and "Join the Game".
For those of you unfamiliar with the term it means i became an official supporting member of KDE eV by donating 25€ each 3 months.
In exchange i get this nice image
A membership card and a welcome gift (waiting for them, i just joined so still not here), the invitation to attend the annual general assembly of KDE e.V. (which doesn't mean much since i'm already a KDE e.V. member) and regular first hand reports about KDE's activities.
That's cool and it's what the webpage lists as benefits, but I think the other huge benefit I get is that KDE has a more stable source of income (it's better to have 100 people donating 100€/year that one donating 15000€, because that one might decide otherwise for next year and you take a big hit).
So if you like KDE and want us to keep doing development sprints, paying for the hardware, etc. you might want to Join The Game with me so we get a more stable source of income.
Of course you can also donate a single time via paypal (and other means) at http://kde.org/community/donations/
but I sincerely think being a member of Join The Game is great and after all it's just 0.28€ per day, of course we live in though economic times so only you can decide if you can afford to be part of this great club ;-)
