Help a Dummy

How do I create a clickable link in my posts, instead of just the URL address that I always end up with? Thanks in advance!
look below... "No html but you may use mark up tags" click on markup tags. it's really easy.

Each tag must include both parts

something said
- shrink and center the quoted text - makes the email address clickable - shows the address as clickable link
title - creates a link with a nice title

The [ and ] are square brackets, next to the letter P on your keyboard.
The second tag must have a forward slash / found under the ? on your keyboard.
Web addresses must start with http. It can be the address of a page OR a picture.

Best, Jeff
