Whew. I'm relieved that you've shown us how to do this list properly, Nemo121. For a minute there, I thought our praise for excellent and upstanding opponents was being improperly displayed. Now that it has your approval and repeated input into the process, I can rest assured.
That being said, I can tell you that listing of my PBEM partner herein (USSHenrico) was based not upon popularity or 'riven with bias', but a culmination of many other factors. This includes subjective assessments of his communication style, adaptability to impediments to gameplay (adoption of HRs as necessary), acceptance of interruptions in the game cycle, willingness to teach and willingness to learn. My listing is also based on a culmination of objective factors, such as turn 'turn around time', frequency of interruptions of gameplay, duration of current game (very important track record) and adherence to previous agreements (e.g., HR fighter sweep altitudes).
I am currently playing three PBEMs, yet I listed only one opponent on this list. That doesn't mean that my other partners are wanting, it means that USSHenrico is the one that I would put into this 'great' category at this time based upon the factors I cite above.
Accepting a PBEM opponent is like accepting a long-term relationship. You're going to be with this person for a long time based upon a common bond. Having some feedback from others ahead of time is a great way to increase the chance that your partner is a quality one.
How refreshing that Azpresto / Wobbly is looking at this from the positive point of view.
