The ASF has produced a range of graphics speakers and others can use to publicize ApacheCon and the talks. Add one or more to your blog, put a link in your email sig, and so on!
The full list of banners and logos is available here, but to give you a taster here are a few you might want to use:
ApacheCon Europe has an entry on Lanyrd. We ask that all speakers to list themselves on Lanyrd, along with their session details. All attendees are encouraged to list themselves as attending on Lanyrd too, to help your friends discover the event!
Thanks to some great work by Christian Grobmeier, we have a lovely flyer designed which you can print out to help spread the word. Whether that's at work, at University, or at other events, please do help let people know about the great event we've got coming up!
