It's hard when there is not a ton of action on a board. People tend to move on when they don't see enough response or activity.
But, what I've found is that your core people will stay. And sometimes there will be lots of chatter with them and sometimes not so much. It can take a long time to create friendships and stability on a board. And then slowly, but surely it grows.
Another thing that makes it hard is when you are talking about a board that's about an "event." Like adoption or IVF or the DI boards. Once the event has taken place then it seems people move on and don't feel so comfortable sharing with those that haven't reached their "event" yet. So, we need to concentrate on making it a friendly place for both sides of the equation. It's really important for those of us still waiting to hear from the veterans! We want to know that dreams do come true and that yes, the waiting is worth it in the end and we need to hear the stories about how on earth they did it! Then there are a ton of questions that come along with bringing a new child into your home. If people will stay they can help the ones that are new to the game.
Anyway,

I went off on a tangent there... Sorry.
If you can find another host to help you Kristine, that helps alot. So at least one of you is here all the time. You are doing a wonderful job, but one person can't be here all the time. KWIM? You need to have someone answering posts every day and also posting a new post/question/thought/idea/subject/article as often as possible as well.
Once you have a few consistent posters a weekly GTKY/poll post is always fun.
We could have a blinkie made to link anyone here from our other boards we visit.

I'll have to think on it a bit and see if I can come up with any good ideas.
