A frequently asked question is “How Do I Add a Link To My Post?  The process is actually very simple.
1. Open the post.
2. Place your cursor at the desire location within the post. Or, if you want to link specific text, highlight that text with your cursor.
3. Click on the “Link” icon* which will open a dialog box. Paste or type the URL in the designated box and press the return button.
* Note: Beside the Add Link button is a Remove Link button.
