Once you have a URL (a web address):
1. put a < symbol.
2. Then write A HREF=
3. Then put quotation marks around the entire web address.
as in "http://www.davisenglish.com"
4. Then put a > symbol.
5. Then put the title of the source you are linking or a title that identifies it.
6. After that put another < symbol.
7. Then put /a
8. Finally close it with a > symbol.
I am sorry, but I am not able to show you what it looks like. If I do, the post just turns what I am trying to do into a tag.
I will work on that.
