@firstname.lastname@example.org so, let me tell how how fork is to be used, before the Yarn Police comes around, and write you an infraction. A fork is used when the reply twt you are about to write goes astray from the main topic of conversation. That’s it!
Now, fork can also be used when you want to reply to someone, and you want your reply leaving no doubt which twt you are replying to. This easily applies to long, to very long, yarns. If you have any questions let me know!
