Renkei / Skillchain Program/WebsiteFollow

Hey, well, with all those printed out renkei lists around, I was wondering if anyone had some sort of program or website they use?

For example, You could enter in what type of weapons the party has, and the output would be a list of chains that the party could do. You could output every option, or give an average level of the party and it would give the highest possible with that level.

A website or program like this would be my best friend.

This rules!
