How do I post a message to commuity

I posted a hello Taiga community post introducing us and our migration to Taiga from Pivotal Tracker. The only place I see the post is in my Messages in Box. did I do something wrong or is there some kind of moderation between me making a post to the community and it being added for anyone to see?
The post in my inbox is here https://community.taiga.io/t/pivotal-tracker-migration-to-taiga/5826/4 I did invite a couple of people who seemed interested in Pivotal Tracker Migration.

I have read the contributors guide on making posts but feel like I may have gone down the wrong flow somewhere

Any help welcome

Hi there!

First, welcome to Taiga, we hope you enjoy your stay!

It seems you created that as a personal message instead of a Topic. Try creating a topic inside one of our categories and see if that appears as a topic.

Best!

Thanks Charlie, will give it a go, I will get there, thank you
