I assume you are asking about this site? https://www.smogon.com/cap/pokemon/
That's the old layout damn, shit hasn't been updated in years
No one has access to it? That's odd, how'd that happen?
The longer answer to the original question is that "no one who has the knowledge to update it properly has access to it".
We don't have a list compiled currently, but here is a quick timeline:
The Introduction to SS CAP thread is a bit out of date because it doesn't account for some of the buffs and nerfs we've done since, but it offers a fairly good picture of how the CAPs currently function in the metagame. If you're looking for original design intent, the EnCAPlopedia features links for the original final product threads for most of the CAPs (barring a few of the most recent ones), and the rest can be found on the main CAP subforum page.
CAP is a mutli-stage, competitive project where the community works together to make a pokemon. When a project starts, concepts submissions will open and users can submit ideas for what might become the backbone of the project. Note that there are limitations as to what can be submitted for a concept. Defining elements like typing, ability, and stats cannot be dictated by a concept. These elements will be decided later in the project but will be influenced by the winning concept. We also do not accept fully designed fakemon.
To elaborate on dex's answer, yes. Legality checks for movepools are lengthy. We need to check for both competitive issues and style guide issues. It requires a lot of availability that the team just hasn't had. We've been working on it slowly (7 submissions/14 movepools total) and should expect a poll soon.
Concept submissions will open when the next CAP Project begins. There will be a dedicated thread for them, so keep on the lookout for that.
Most likely later in January but it could be later.
the chances of Megas returning at any point besides an XY remake are next to none; however, if they do remake, Mega Crucibelle will be legal, yes.
This is a peak behind the curtain or whatever the saying is but don't have concrete plans to look into banning tera, especially because there's whispers of another upcoming suspect in OU. Things need to be SERIOUSLY broken to make CAP take tiering action (see: DLC1 Clef, Duggy being legal for 7 months more than it should have been in SS).
