On his blog, David Sklar has a very quick reminder about the upcoming Pro::PHP podcast that he's doing.

I'll be chatting with Marcus on the Pro:PHP Podcast this Friday, Feb. 24 at 1pm ET. Tune into the live webcast and ask questions!

As he mentioned, you can sign up for the free live webcast here or, if you can't be there, the entire recording will be posted on the Pro::PHP Podcast site (and can be pulled down by any aggregator subscribed to the XML feed).
