@Joseph Kinguse the @ symbol to tag other thread participants or your colleagues.  

@THANH NGUYEN to "mention" someone, type the @ symbol and the first three letters of their name and wait.

Once you type the '@' symbol and the first few letters of their name you should be able to click on the name of whomever you want to mention in the box that pops up below.

Quick tip: when you want to make sure someone on a thread sees your response, tag them with the @ symbol.

@Vincent Mazzaferro from your computer, if you put in the 'at' symbol, then put in the first letter of the person's name, it will pop right up - as long as they're in that discussion, or you are connected with them on BP. 

[tip: not all fonts which are available for download have special symbols such as: (#

Oh, BTW, if you want to refer to a BP member to get them to respond quickly, you should type the @ symbol and then the first three letters of the BP name and a box will drop down below the reply box you are typing in.

@Chai Sag type the @ symbol and the first three letter of the persons name and it will pop up in the bottom of the window.

Rich Weese - Steve Babiak is right, if you either quote or edit your original comment with the link you can just add the - ] - symbol right after the first instance of [url in your post.
