PHP.net as posted a note from the O'Reilly Open Source Convention as a reminder for the Call for Participation.

Individuals and companies interested in making presentations or giving tutorials are invited to submit proposals using the form below. Proposals will be considered in two classes: tutorials and convention presentations (sessions). Presentations by marketing staff or with a marketing focus will not be accepted; neither will submissions made by anyone other than the proposed speaker.

Sessions need to be about 45/90 min long, and tutorials should be 3 or 6 hours in length. There are tons of conferences that will be running all at the same time including: the PHP4 Conference, MySQL and PostgreSQL, and Apache httpd, Java, and XML projects.

So, if you're interested in presenting, hurry up and head on over and submit your proposal - the headline is February 9th!
