I think it can only be done on InLeo. It's not clear how to do it because, in my opinion, InLeo's interface is one of the least intuitive of the dApps.
Anyway, here's how I do it:
- I go to my InLeo page and click on the "Home" icon.
- I write and post a Thread at the top of the page.
All my published Threads are on my "Profile".
Thank you so much I will do just that now.
