I really searched for this answer and didn't want to ask something that is probably very obvious to others. How to I tag a name of someone who sent me something when I post a picture?
Thanks for your patience
As far as I know you cannot tag people, like in FB or instagram, so that they receive a note of it.
Tags here at IUOMA I've only seen in the 'Photos' section: you can add a tag when you upload a photo. But that is similar to tags in blogspot and so, and does not send a note to the tagged person.
