If software on the fediverse such as lemmy and kbin are connected similar to emails, how come I cannot use kbin with my lemmy account and have to create a new one for kbin specifically? Is this just a bug, or have I misunderstood how the fediverse works?
You have misunderstood. You can’t use your gmail account to sign into an outlook account. However, you can email people with the same or different email providers.
You can’t use your Gmail account with let’s say Hotmail. I think that’s the analogy very commonly thrown around here - I’m not sure how accurate it is though
If you create an account with Gmail, can you then login to Yahoo! email and send emails with that same account, or do you have to have a Yahoo! email address to send emails from their website?
You can send an email from an @gmail.com email account to an @yahoo.com email account, and vice versa. But you cannot send an email from an @yahoo.com account on the Gmail website.
