Flyboy, welcome to the site...
First off you need to decide if you want to host with the Ouka Chat Server (OCS) or with WinMX. Technically they are two separate hosting programs.
If you decide to use the Ouka you will be able to connect to the WinMX and your room will show up on the list of rooms without you doing anything special. The program finds WinMX for you.
Keep in mind you dont even have to have WinMX running for your room to be open with Ouka, its just a way to use both.
When you create a channel name with Ouka its only necessary to put in the text of the name. No numbers, the server will get those for you.
Then with your WinMX you simply find the room and join if you want to.. since your not actually hosting with WinMX the config2 file although, helpful to see the commands available, is not needed.
Once you have the room set up you should be able to enter with the MXC bot also, if it says "Remote host did not acknowledge" then you should try the loop back inter face to get the bot in.
Now.. set up your room, and dream about somethings more nice.. hehe
Lets us know if you have any more questions..
