[Mailman-Users] hyper-mail vs. pipermail??

[Demian Hanks]

I am setting up a new listserver, and seem to have 
mailman running fine, but I'm thinking now that I 
like the look and feel of hyper-mail's web-archives
better than pipermail. No-offense to piper's developer.

Has anyone tried to make the swap? Is there a reason 
not to do this?
And finally, what is the best way to go about making 
this change?

Thanks,
Demian
