Wiki Frustration

I have to say I'm a little frustrated with my first wiki experience. I had the idea that the kids would edit the wiki daily adding the characters, summaries, and vocabulary that we had read about that day. The problem is that we can't keep up. We are starting chapter seven tomorrow in the reading, but the wiki is barely through chapter three. I really don't want to give up on it, but we just can't seem to find time to catch it up. One problem I know now is that the groups are too large. Putting six kids together to accomplish a task is just too much to ask. The next time I do this, I will most definitely make them smaller. That may be something that I have to do anyway to finish this one. We'll see.
