What @trohde said. Great!
I started my own Go club about 8 months ago, so let me offer some advice.
To get new members, most importantly you need to get the word out anyway you can. A couple good options are registering your club with the Go organisation of your nation (American Go Association, European Go Federation) . Also consider advertising your club on sites like Meetup and Facebook. And of course, announce it on the OGS forums. (I even plastered my city [Chicago] with paper flyers. It's over the top, but it works! It brought in two members).
Second, consider investing in some equipment. One board and one set of stones are fine for now, but if you get any more players they won't stick around if they can't get a game. And yes, you should have a 9x9 or 13x13 on hand. You can make your own, or I believe there is a printable version somewhere on the web. I look for it later. Anyone have the link?
The most important thing is to hold regular meetings. There is nothing worse that someone new coming out to your club and not finding it. They will never come again.
You already have a leg up, you already have one member. When I started I had zero, now I have eight. It was slow going at first. For the first four months, I had zero attendance! I thought about disbanding the club . But be patient. Now my club is steadily growing. Good luck!
