I often see in posts a previous posters name appear in the quote like @bill plunkett (in blue). How does one do this?
Type the at (@) symbol and begin typing the first persons name, followed by a space, then the last persons name. Or if you only know the persons last name, then type the 'at' symbol and type the last name. The program will start autocompleting the name.
Autocomplete couldn't find your first and last name on my machine, it might be that there are too many Bill's. When I typed @ and plunkett, your name came up, and i selected your name with the mouse, as shown below.
