You can add a group posts widget to your home page. It will show you what posts are active in your group.
You can sign sign up for the daily digest. It will email you every post that activity from the day before.
You can click on the groups tab at the top of the page and then my stuff and there is a link for my posts. You can use it to look up all of your posts.
In the group you can click the green search posts link on the left and enter the "title" of your post.
