Hi Glaucus

Braden is overseeing this PBEM but is a little off-colour and not on-line at the moment. In his absence I will answer your questions:

1) The rules and difficulty for the PBEM can be found in this thread:

It will be Very Hard Campaign and Medium Battle difficulties.

2) The PBEM's used to be played by e-mail but are now uploaded/downloaded to and from the net. The name PBEM remains and the principal is still the same.

Hope this helps.
