BP Social Display Options

Hi, I'm new to WPMU Dev so please bear with me on this one. I'm pretty much fine with installing everything but I have a query on the theme I installed. I'm using the BP Social theme & all working perfectly - thanks guys for an awesome theme :wink:

I am running Buddypress on a multisite basis & I wondered if I could simply have only the splash page showing on the home page or welcome page? It seems that when logged out the page displays 'Please login and Add Widgets to this Column' where the theme places the widgets once logged in. Ideally I would prefer for that not to show & just have the splash page advertizing the site & showing the sign in or sign up box or link (the default graphical area).

Thanks for all your hard work, you guys rock!
