Woody, I'm so glad somebody's been able to make it work!
I'm going to try a different teaching method, with numbered steps as Gail recommends. This method will bypass the link icon and tell you what code to type.
1. Go to the site you want to link to. Write down its URL. For LIGHT, for example, the URL of the home page is lightpoetrymagazine.com/revamp/
2. Back on the Sphere, get into a post that starts or replies to a thread.
3. Type an opening square bracket and an equal sign.
4. Type an opening quotation mark.
5. Type the URL you wrote down.
6. Type a closing quotation mark.
7. Type a closing square bracket.
8. Type the word or phrase that you want to act as the link, the one that will show up as blue and underlined, such as LIGHT. You don't have to underline them. The program will do that.
9. Type an opening square bracket, a slash, the letters URL, and a closing square bracket.
I'm going to follow my own directions now.
LIGHT
Now I'm going to try Roger's directions, just because I've never done it that way.
The words that will be the link.
Son of a gun. That IS easier.
