So I have an index homepage and the forum installed in a forum directory. However due to budgeting issues I'm unable to complete the index homepage the way I had hoped. So instead, I was thinking of using a Portal system and having that as my homepage. Problem is, how would I set it up so that when a user types the main site address, they would be shown the portal page instead of the index homepage I already have? Would I need to reinstall the forum in the main directory?
