First, unlock it. Then move the mouse over the html for a second and a grey border will appear around it. Move the mouse over the border and it will change to a double ended arrow (if that's what you call it), drag it to the desired size. Then lock it.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
