I'm glad you got around to signing up. I'm in the same boat as you.
It was recommended to me that a good way to convert some warhammer FB players over to mordheim was to find a local WH/table-top wargame shop and see if you can run a Mordheim night, and promote it at a WHFB night... It'll take a little while to get started and a little work, but It's a great way to get a Mordheim league going.
I think it's a great idea, but the closest miniature shop is little over an hour away, and I don't like using that much gas/time every week... so I'll have to wait (till I become a millionaire or something....)
Until then, I just stay content with the hobby of making buildings and models. =]
Enjoy the Forum,
