quick question…

I had dinner with Sarah and Leo tonight, and we were discussing our wiki project. We decided it would be smartest to post all communication on the blog (as opposed to creating a fb page or something) so other students could learn from our mistakes (and hopefully our successes!) and comment if they so wished. We were just wondering if there was any way to possibly “tag” a blog post, to ensure the other people in the group see it? Do you have any other suggestions? Thank you!
