i enjoy it a lot but at times it can be a little intellectually intimidating , there are a lot of very intelligent ,professional people on this site , and at times i feel a little bit dumb,

I can speak for myself only ... if I'd let feeling "dumb" keep me from posting, or the odd remark ruffle my sensitivities I never would have gotten past "Stranger" designation!
It took me awhile to catch on to link posting and using the little emoticons ... ... but Private Messages to long-timers on the board got me sorted out in no time which is miraculous considering I am pretty much cyber-impared!

Sooo, to you Duncan, and all the folks who are timid about posting ... just start running down that wharf and LEAP IN!
The water's fine!
And, do not hesitate to send a PM to me and I'll help with any (basics) that I can, and try to refer you to the more savvy if I do not have an answer for you.

C'mon, You are only a Stranger once, regardless of the title you're sporting.
Aloha
wow
