What is the Welcome module?
Well, this is of course. Because you've just arrived, this module will be shown a set number of times (page views) before disappearing. The text being displayed and the number of times to show it are totally configurable. You can even include tokens to be replaced with text. For instance, this module will be shown for 9 more times before disappearing. Go ahead and reload the page in your browser (F5) a few times to see the number change. After it gets down to 0, the next refresh will hide it completely. If you wish to hide it now, click on the Hide link. You can also configure a keep hidden link so the user may dismiss the module for good. Just think of all the places on your site where this would be useful!
