Thanks for the input guys, I really appreciate it!
So for our discussion points:
1. CS Rarest Pet Guide seems to be a favourite but let's keep suggestions and opinions coming!
2. Separate posts on the same guide sounds like a good scope but we can always change our minds later c:
For our introduction post I am thinking we should cover these things:
> Brief summary of purpose
> Rules for when the guide's complete (what should/shouldn't be posted here)
> Contents (links to other posts on the front page)
> Resources (links to the rarity guides)
Meduz I agree that URs would be easiest to draft next. They will not be so easy to provide trading advice for though. Their rarity tags often aren't comparable due to being released in different years and under different rarity systems.
