Everyone asks how do I change orca to to forums. This has always been a hot topic, and this forum post at boonex seems to be right on.
I've applied it here at dialme.com if you notice in the address bar orca is now forum. I've tested this for a week now and all is well.
If you have a moment and this is something you have been looking for check it out. It's a very easy mod, and only takes a few minutes of your time. For Dolphin version 6.1.4. Otherwise see the users posts for other versions.
Good Luck and happy modding!!
