New here very surprised at the lack of resonant post's

[del]

Glad you enjoyed the exchange Dan.

I have a question for you. You name is Dan but your screen name is Del. Both begin with "D" and each is three letters. Why not just go with Dan for a screen name, specially since you sign your name at the bottom of your post.

Great question Rudy no.1 Dan is already taken as a username by a very nice gentleman here and no.2 Mathematics was a hobby of mine at one time but I encourage my friends to call me Dan.
