If you want to let people know about your account on here, it's important to include your full account address (also known as a "Fediverse address").
If you paste a full Fediverse account address into the search box on any server, it will always make the account profile appear, even if previous searches drew a blank.
You can exchange account addresses with others just like you might exchange email addresses or phone numbers.

@feditips Im pretty sure I've heard "webfinger ID" come up more since I think this is the first time I've heard "fediverse address". YMMV, and my brain is toast from this morning.
