Great idea Chin, I would definately contribute my experiences. I was just going over some of the literature I have on fish, and well, it's out dated. Most books will rate each fish's difficulty in care, and list it's compatability with other fish and inverts. As well as food types and various other husbandry notes. However, none of the books I've ever read indicates where they acquired this data from. I always get the impression that it's all the author's opinion, so how would my skill stack up against the author of the book?
Having an index of our own would allow me to come up with my own opinion on weather I should buy a fish, based on how I feel my skills are compared to other reefers that I already know. Far more valuable to me than any book I've read.
As far as the physical statistics of this kind of poll are concerned, have fun!
At work I deal with stats a bit, and by the time I'm finished developing the perfect chart, which accurately indicates the multiple variables I'm looking to portray, I usually have a head ache, and my neck is numb.
I'll be interested to see how this developes.
