When posting an URL you can insert a "Hyperlink" to click on instead of the extra long URL. Just type a short descriptive word(s) that identify the URL, highlight the text(left click your mouse, and roll it over the text) once the text is highlighted click the "Insert Hyperlink" icon on the "Format" row, make sure you select the "Prompt" option in the drop-down box in the "Format Mode" choice, this will pop-up the dialog box to insert the URL...
