WotC is operating a DM Hotline until October 11th.

Here’s the post on the WotC forum:

If you have a question about running 4th Edition Dungeons & Dragons, whether it’s a technical rules quandary, or would simply like to improve your DMing skills, here’s your chance to speak directly with the folks at Wizards of the Coast! Expert DMs-including R&D’s Mike Mearls and Rob Heinsoo-will be on hand to field your calls on the DM Hotline.

The DM Hotline takes place for just a few short days: October 8-11, between 2pm and 6pm PDT. If you’re looking to improve you game, we encourage you to take advantage of this opportunity to connect with Wizards of the Coast DMs! Simply call toll-free (800) 878-3326.

Please note that at this time, the DM Hotline is only available for calls originating within the US and Canada.
