CPanel Directory Index gives error

I know that I should probably post this in ORCA...but it will be read here by more people.

Site is up and running...no probs with Orca....seemingly no probs with a/v chat.

When I go into my CPanel to add a DIRECTORY INDEX (Dolphin and such lie in a folder inside the root URL) ... after updating and when I click on Forums.... it starts giving me a page listing the file tree for ORCA....ugh.

Delete the Directory Index file from CPanel....it goes back to normal operation.

Then....I tried a re-direct....that was even worse....gave errors to the main Dolphin site... wouldn't open.

So my question to you all is: How do I get my URL www.mysite.com to bring up www.mysite.com/community/index.php?

Thanks again for your input!

Any workarounds.....

Also...when the Directory Index in CPanel is on....

When the main page loads and you click on the Live Cam or any other  link on that page that brings up a new  media window...

It goes to the file tree in the background...UGH.
