I do apologize if this is in the wrong place.

Hello Awers,
I've been thinking of making a forum for my home region in the new year and have no idea where to begin and I'd like to have it up and running in the new year.
I had the idea to make this for a while and recently my writing group has drifted apart and no one is showing any interest (other than myself) in getting together any time soon, so I thought maybe putting the forum up would help gather fellow writers and make it easier to form groups/contacts closer to home.

And now to my questions, what kind of content should I have on my new forum and how do I attract members?
