Heads-up for Tuesday afternoon

I'm doing a live online chat with John Hemry (writing the Lost Fleet books as Jack Campbell) on Tuesday afternoon at the Suvudu site.   We're going to be talking about research methods (unless we get off topic, when our esteemed editor will no doubt restrain us!!)    We thought the differences and similarities of doing research in SF and fantasy would be of interest. 

By all means, join the conversation if you have time that afternoon.  4 pm EDT, 3 pm CDT and so on.
