Just a heads up that Gmail continues to move some Vortex messages to the spam folder. If you use Gmail, an easy way to find them is to go to the spam folder and search for Vortex. Nearly everything in the results will be legitimate Vortex mail.
I suspect the filter they're using to send messages to the spam folder is the degree to which pseudoscience is promoted. If you wish to avoid the hassle of people looking for your message in the spam folder, you should discuss only orthodox science. Eric
