Unfortunately, the feature is (extremely) poorly labeled as “Rename”. Ever since 2016, I petitioned the administration to change it for the very reasons you’ve stated: no one knows what it’s for nor how to use it, and many don’t even know it can be done. If it were called “Edit”, someone might mistakenly believe its function is for editing. My pleas always fell on deaf, apathetic ears. (Sigh.)
Caveat: this is not to say that there’s anything wrong with you being in love with her, nor does it mean that I dislike her, hate her or do not respect her. I like her very, VERY much, it just doesn’t rise to the level of agape the way it does with you. Bedsides, the administrator didn’t leave you outside of a jewelry store in Athens with a bag of stolen gems and no getaway car in sight just as the gendarmes were closing in. It’s in my favor that the Greek lady prosecutor had a thing for me, or I might be appearing on an episode of “Locked Up Abroad”.
If you are using a phone, I can't help. If you are using a computer, just above your question you will see 'rename' 'edit description' and 'delete'. Posting videos is a different question...it depends on the source and I only post from youtube.
