Good morning Lucky! 
Welcome to the CP forum!
Yes please do post an introduction when you get a chance, or maybe I missed it already....I suppose it's possible!
The members here would love to get to know you better, and we look forward hearing from you soon!
Also!...Tina is correct, that you can edit your profile and place what ever you want in the signature line, but I will add one more thing to her help....and that is, when you post or reply, there is a section at the bottom of the body of your post that allows you to select
"Include signature (can be modified in the profile section of My Profile"
Remember to check the box if you want you're signature information to show up along with your post and or replies.
Hope this helps!...Enjoy the forum!
