What do you mean? Do you want to ask questions or start a whole new site?
i'm new here. could I make my own forum here cause thats what I was searching on google...
This probably isn't the place then. There are sites that offer forum hosting and the fees are now reasonable. You could give them a try for your own skateboarding forum.
There is a forum site called "The Admin Zone" for forum administrators. It would be good place to start too!
There are some free forum hosting solutions out there. You might want to dp a google search for free forum hosting.
I'd be interested to learn what search term led you here, if you were looking for web hosting.
