Hide welcome text if empty?

Anyone know of a way to edit the welcome.tpl file so if the welcome message (Admin → Organize Index Page → Edit Index Page Text) is empty it doesn’t show.



I want to use the welcome message on occasions but not all the time and currently with the code left in the template I have a blank space at the top that I do not want.



Hope you understand what I’m asking here… I’m new to smarty and just getting to grips with it.



TIA
