30 day challenge together?

Hello, I am new to this subreddit and I couldnt find any threads of doing challenges together. So I wanted to ask if it is allowed and if anybody would like to participate in a 30 day stretching challenge where we keep us accountable, report progress and hopefully see some results after the 30 days. Regarding the technicalities, are we allowed to just use a thread here? And regarding the stretch, I have multiple goals so I am ok with whatever the majority votes for. My current stetching goals: hands touch behind back, deep squat(ankle mobility), side splits, middle split (or rather pancake?). I can already touch my toes but I would be up for stretching that more too. Let me know what you guys think and if anybody would be up for a challenge like that. We could maybe even pick a routine or video together to follow. Sorry if that was discussed already somewhere, I could not find it, please post a link if there is one.

TLDR: wanna do a 30 day stretching accountability challenge here? If yes, what stretch?
