I am looking to launch a completely private community in the next few weeks. I've pretty much got it all set up how I want it after almost 4 months of configuration, tweaks and so on. I've basically turned off any sort of guest access but the problem is that if a guest tries to access my community it shows an "error" page "you need to be logged in to do that". Is there any way I can make this error a little bit more friendly i.e. instead of error just show a different message and the login boxes?
