Should I remove the Blog Frog forum box?

The Blog Frog forum box is not getting much use because we now have such a nice group discussion site on Rug Hooking Daily and everyone who is posting seems to be using it.

Do you have any objections or thoughts about whether or not I should leave up the Blog Frog forum or remove it?

My thinking is that it is better if we just post in one discussion box and not split our conversations between two sites. The only downside is that not everyone who is in the challenge has joined the RHD group yet. I suppose I could leave a link in the sidebar to RHD group as the place where our forum is being held so people can easily find their way there.

Thoughts? Preferences?
