Add any "- .../uto" after your name to support it or even become a cofounder:
All the utopian communities grow the best future probability - p(best) - some do it more actively, others simply endorse it by using the word /uto
Many uto communities (e.g. e/uto, chill/uto) let you become a cofounder, usually you'll need to become active there - join, post/repost stuff, ask can you become a cofounder
UTO movement itself doesn't belong to any one community - it's for everyone, this website is a fan-site
Founding your own new .../uto is as simple as putting it in your profile name/description
Sometimes people add .../uto to an existing community (e.g. space/uto) as a postfix - it's awesome, too!
I prefer to use uppercase UTO for the movement only (and I pronounce it Yoo-Tee-Oh), in all the other cases I prefer not to use the uppercase (and pronounce it just YOO-toh): e/uto, chill/uto. The exception is tags like #eUTO, #spaceUTO
I think, you can still be the first to found cat/uto, dog/uto and all the other .../utos ;-)
Be part of many utos - the more the better!
