Sorry to butt in, but I just wanted to mention that you should probably use mentions. If you don't know what a mention is, it basically notifies a person that someone is talking to them. If you don't know how to do that, I'll teach you. So, first of all, there are three ways you can mention people. The first is to just type [@the persons username]. Simple as that. The second way is to use the @ button on your post tool bar, which is the bar above your text box with all the buttons. All the way to the right, there should be a button that says preview. To the left of that is the @ button. Press it and you get this: [@Username]. You then just type the person's name in it. The third and final way is, for me, the most popular way. First, you go up to a post made by the person you want to mention. Below their signature, in the bottom left corner there should be three small buttons and two big buttons. The big button with the word @Mention automatically puts a mention for that person in your post. 

And that's pretty much all I can teach you about mentions! Hope that was helpful! ^_^
