Your newsletter is very useful, but is there a cumulative index that I could search. I am saving your newsletters, but this is a slow research job if I think of an issue that I need help on.
you can either check out the newsletter archive here (includes the newsletter starting from March 2010) or the entire MakeUseOf Archive here.
By the way, the new version of the newsletter includes bookmark to Del.icio.us links underneath each story. This makes it very easy to bookmark the favorite articles to your del.icio.us account.
We enabled the archive recently, so you can catch the past issues here.
The Newsletter is just a compilation of stories from the website. I'm not sure if an index exists or not but if you're ever looking for answers on a particular topic I suggest searching the site for it. You'll be amazed at what comes up!
