Bob,Longroof79 l agree with your last post, but everyone has different comfort zones. At the same time l won't remember anyone's real name unless l met them in person buts just me !
You can call me Jack...I'm not hiding behind a screen name. As far as remembering peoples names, it's not really necessary, but many of us are on a first name basis....some don't care to disclose their first names...to each his own I suppose. I think it's a nice personal touch.
For the most part, I'm a friendly guy until I get irked about something.
