Ask yourself sincerely which one is best... (you know the features of each one)

"D" is trying to jail you and is gently sweet talking you by advocating sending
unencrypted email.

You messed up big time "D" by telling folks to send unencrypted posts!

"D" advocates sending unencrypted posts in the following link
14th post down...

NEVER SEND ANYTHING UNENCRYPTED!!!

"D" is also using anonymous remailers, can you see a pattern? LOL

"D" may not be what you think, possibly not one person but a bunch of feds lurking
in here. Don't think for one minute the feds or cia are not here, they're here
alright. Only feds would advocate sending unencrypted posts to newsgroups!

DON'T GET FRIENDLY OR TRUST ANYONE HERE, THIS IS NOT A DATING SITE!

One last thing... get off Hotmail, Gmail or whetever you're using and send
your email encrypted so that your ISP or email provider can't profile you.
