Invitation to join the preaching blogs group

I've just put together a new Blogdigger preaching blogs aggregator. It's a handy way of accessing blog posts on the topic of preaching the gospel. Each day Blogdigger creates a group page in which the latest posts from each member blog are linked. Right now the members are Expository Thoughts, Soul Preaching, Theocentric Preaching, and Transforming Sermons.

The group is open to all blogs with a strong emphasis on preaching. If your blog is one of them, you're welcome to be a part of the group. If you would like to add your blog, or know of another blog that ought to be in the preaching group, please let me know. You can leave a comment on this post or e-mail me at the address in my Blogger profile.

Update: If you've checked lately, you've no doubt discovered that the Blogdigger groups have been gone for quite some time. It was great while it lasted, and Greg Gershman at Blogdigger was great to work with. Does anyone know of a similar service operating now? I don't know if I have the time or motivation to administer it, but I'd like to be part of one that already exists.
