Hi Apostle,
I am pleased to be on your list, though I think the quality of my posts have been rather poor of late due to time constraints and crankiness to rival Moose.
I also really enjoyed debating with Tranquility Base who was always willing to listen to what his opponents said without just dismissing their points outright. Another creationist I can't say I enjoyed debating but I found stimulated the most active evolution discussions on this board to date was Peter Borger. Funkmasterfreaky was also a very pleasant debater. I think it is usually a combination of people who stick around and contribute over a longer term and do so consistently (applies equally to the evolution side) and are in some way responsive to what is being said. Even if hostile.
