excel noob, inputting my user name into a cell

[/\ndy]

Am looking to have a command button on my spreadsheet that inputs my windows logon/outlook name into a specfied cell, does anyone know how I would go about this?

Thanks

Thanks for reply, I've tried that and similar methods, but whenever I try to declare the function in a cell I.e =username() the cell juts shows #NAME?

Any idea what might be causing this?

Thanks for all the input,managed to get this working. Another issue I've got, does anyone know how I would pull the header information from a web page to a specific cell in excel?
