Nice to meet you! #QOTO is so great.
I like using "Federated timeline" with hidden domains in "QOTO Default Theme" or "Material Theme (dark)" very much (like a image. In addition, Twitter button is https://addons.mozilla.org/ja/firefox/addon/birdsite/ ).
Furthermore, I am interested in "NextCloud" and "Discourse" of https://qoto.org/about/more .
I don't know the details yet, But Many Thanks #QOTO !
@puzzl Hello and welcome to Qoto -- I am glad you like the place are are enjoying it. 😃
I like the Dark Theme, and run it in full screen on my laptop. With a nice add-on for Firefox called "Collapsed Mastodon" it uses all of the screen - as shown in this screenshot I am taking now.
It add a Toot Editor right below the post I want to reply to. 😉
@puzzl For using the Discourse Forum and the NextCloud service, you just need to sign up for them -- each is a separate account from the Mastodon instance, unfortunately. We suggest you use the same name as you use in Mastodon, so people can recognize you more easily.
* Discourse forum is at : https://discourse.qoto.org/
* NextCloud is at : https://cloud.qoto.org/apps/registration/

@puzzl Wonderful, I am glad you liked the Discourse Forum! I think it has great potential, it complements Mastodon well.
