So, I want to include a link on my den page to a spreadsheet I'm putting together. The spreadsheet is going to have a breeding history, and I want to use this spreadsheet as a data set for statistical modeling.

1) Are external links allowed on our den pages?
2) Is doing this against the rules? I want to do it because I'm trying to get into data science, but I really can't tell if it counts as "game breaking" since the specific %pass rates for the Celestial base have never been published (and I'll probably figure it out if my data set gets big enough.)

Thanks all!
