@Megan You crank up the trunk, type in some stuff, and then toot it!
Well, I think you already figured it out because we can read your post. ;) You can always ask the community for help if you can't figure out something!

@Megan several options: have a look for people you already know from other sites, (https://pruvisto.org/debirdify/) dip in your local timeline, or search for a hashtag.
And hello!
