Chris Shiflett has posted a reminder of some of the upcoming Open Source related conferences for the next few months including:

• php|tek (in Chicago)
• eLiberatica (in Romania)
• OSCON (in Oregon

He's also included brief summaries of what each is about for you to pick out which you might want to attend. In the comments of the post, he mentions yet another conference (just passed unfortunately) for UKers - the PHPConference UK.
