If you're attending OSCON this year, be sure to check out the PHP Lightning Talks being hosted by George and Laura:

Lightning talks are a collection of 5-minute talks given by you, members of the PHP community. A mainstay of the Perl side of the convention, lightning talks are an exciting format and an excellent place to showcase new ideas, ask questions, or rant.

In the meantime, you can learn all about lightning talks, read some tips on giving lightning talks, or submit a PHP lightning talk proposal of your own to lightningtalks-oscon2006@omniti.com. Proposals are being accepted until 21 Jul 2006.
