Open up your User Control Panel and in another tab/window open up your journal. On the UCP page click on Edit Signature and within the input box either type in your journal name or copy and paste it from your journal. Once you have the name in Edit Signature input box, highlight the entire name. Go to your journal and copy your journal link found in the very top of your tab/window. In the Edit Signature page click on the icon that has the world with a link underneath it, it is just to the right of the emoticon icon. In the input box that pops up, paste the journal link, click on OK and then save your signature. To make sure that the link works click on it to make sure that it opens up your journal.
No problem you are welcome. If you want your title to be your link to your journal without the actual link showing, then make sure the title is highlighted before you click on the Link button to add a link to your signature.
