When I started my Forumer forum, the website name I wanted, realityisland.com, was taken so I registered realityisland.net instead. Recently realityisland.com became available so I registered it and added it to my Forumer site as the selected domain. Now the realityisland.net redirect isn't working.

Is it possible to have two domains redirecting to your site or do you have to choose one or the other?
