Potential email problems

For some reason, some of my emails have been ending up in people's "spam" folders recently. I am not quite sure what the problem is, but if anyone thinks they should have received an email from me, I would ask you to please check your spam folder. Among other things, I recently sent out a mass email to presenters at this week's upcoming Third Annual Philosophers' Cocoon Philosophy Conference, and am worried some people may not have received the email [which contained some very important information]. If you did not receive that email--particularly if you are presenting at the conference via Skype--please email me at marvan@ut.edu and/or send me a facebook message at your earliest convenience.
