Ok, I have just got a free Invision board host from www.hosted-forum.com, and have activated IPDynamic but I dont know how to access it, the home is just the normal forums.
By IPDynamic I hope you mean the snazzy front page you can get for Invision (www.programmingforums.org - example). If it isnt, I have been misinformed, and hence I need to be pointed in the right direction.
