Does anyone out there have a windows mixmaster client? (or a pointer to one?)

There are none.

Also, I am having a LOT of grief trying to get the alpha.c2.org remailer to work for me... (yes, I have the help files)

Could someone walk me through it?

You mean the nym server at alpha.c2.org? It seems to have about a 1 week delay on it... Be sure the reply block that you give it is your own, and that you tell alpha which remailer the reply block goes to. Don
