Sure, I can help you!
When you are writing your entry highlight the word(s) you want to have linked to your site...........then click on the linking icon above, it's on the first row. Check out the graphic below....
Then a window will open where you will add the URL of your site, then OK, and that's it! :-D
Hope that helps!
I wanted to reply to your post with my help, but I couldn't add a graphic in the reply (only when I added a new entry)........I need help too, LOL
