Welcome Rich, glad you could join us. btw I got my feet wet on flat stock as well, but haven't touched a sign or poster since deciding to downsize and specialize in shirts back in the 90's.
One thing that I have always pushed on forums on which I participate, is to give as much information publicly as possible.
PM's and emails are great for emergencies, and getting board buddies through sticky situations, but when questions get asked and answered right here in the open, literally thousands of people can benefit.
So, Fresh Baked, it's on you. Ask away!
