Hi Aaron,
The logo you're linking to was created by Joel Birch who was very generous in creating an awesome jQuery image.
As for the new logo, you can use it in presentations and the like but we don't allow the jQuery logo to be used for merchandising (i.e.: t-shirts, mugs) and other commercial items without our express written approval.
If you have a specific usage that you'd like for us to review, please email me directly.
Thanks, Rey jQuery Team Aaron Barker wrote:
In a previous thread (http://tinyurl.com/jquerylogousage) permission was given to use the old logo for printing on t-shirts and stuff. The source files were even provided. How about the new logo? Is it still ok to use? Can we get the source files?
