I've been working on the newsletter today. I've put together the basics through February 2011. It saves me a lot of time and guarantees that the newsletter goes out, if I do it this way.
The drawback of course, is that I use articles published by other folks, so they may not be as well written as if I'd written them. I try to add something relevant to each issue, but that isn't always possible.
However, I can plan the issues better this way, too. I can revolve around a certain set of issues, plan the deals with the merchants, and otherwise help my readers to focus on related areas of cats' lives.
If there are any areas my readers would like to see featured, I'd love the feedback!
