Hi Dick,
URL is just an internet address, like
http://www.the-gauge.com/
(Uniform Resource Locator, I looked it up
)
If you click on your name and "View Public Profile" on the left of your above post,
you will bring up a new screen with your info in it. At the upper left you will see
"User CP". Click on this to got to your User Control Panel.
The image tag is the characters in your reply. The URL contained between
[img] and is the address of the picture you are linking to.
I think that's right. Some of this stuff you don't really need to know, like
the image tage, which is inserted automatically for you. The way to get
more familiar with this stuff is to just click on things and see what you get.
You're highly unlikely to break anything using a web browser. (do you have
anti-virus and anti-spyware programs installed?)(sorry to bring it up, but it
sounds like you may not)
