Self promotion is against the rules in General Development.
You can make this post in Get Feedback, if you are looking for people to try out your project and give you feedback.
Alternatively you can post it in Release Announcements, where you announce to the world your new awesome creation is now public!
Whichever one you choose, make sure to read the rules of the board before posting, as they will help you post in the right place, and include the right information in your post. Also for future reference, it’s best not to make duplicate posts about the same topic.
Hope that makes sense. Congratulations on the release! Wish you all the success :)
