I hope cross posting is ok...

First I downloaded the key from the keyserver with:

        gpg --keyserver --recv-keys 0xE60F7299

I did this with the following:

        gpg --edit-key 0xE60F7299

and the "sign" command.

If you mean write out a new _file_, no, it did not write out a new file. Perhaps this is where I went wrong.
Should I try this on a file containing the old public key instead of on a key downloaded from the keyserver?

This is gpg (GnuPG) 1.0.6 BTW

Ok, well this is what I obviously don't know how to do corectly. GnuPG users: how do I do this?

How to do that is currently beyond me :-/

But I don't have one :-) that's the whole problem. There is no separate revoke cert that I can see.

GnuPG users _ is there a way I can make a revoke certificate as a file, that I can import back into WinPT?
