I mean whats the difference they all bring you to the same place if you don't know what I'm talking about look at the top of your screen
The difference is when we were testing a portal the 'home button' would take you to the portal rather than the forums. Now, the home button only serves as a scapegoat on bugged pages. Occasionally our custom pages will bug out, and the home button happens to be the only thing functional in that case. I can look into the issue further, and remove the home button once I have that insight.
