If you dont want to add a link back to Writers Cafe home in your blogroll you can use a method called a blind link. You can see this on my blog, www.tweekniks.com/katesspace , labeled Back to Writers Cafe.
1. Go to Appearance/Menus and click on Create Menu
2. Name the Menu and then go to Custom Links
3. Type in http://www.tweekniks.com/
4. Click Save Menu
5. Go to Appearance/Widgets and click on Custom Menu and chose the menu you just created from the list. Dont put a title in the Widget and the link will just show up as a link, however you can add a title if you want to add other links to this menu besides the back to Writers Cafe.
6. Move the custom menu to the sidebar.
And you are set to go!
