As you may already know, I’m always searching for interesting topics that I can use to write new eBooks, tutorials or that I can use in an instructional video. But sometimes it may not be necessary to do all the tedious work by myself if there are other resources available on the internet.
Some days ago I found this post from makeuseof.com in my google reader listings and I downloaded the PDF file “The Ultimate Guide To Gmail” from their website. I haven’t read it yet but I could see from a first overview that it might be a valuable document for you. Meanwhile I have read it myself and it’s really a valuable document. Couldn’t have done it better.
Let me know in the comments if you like the style of this document. I will have a closer look at this and other PDF eBooks from their site. If you sign up for their newsletter, you can download a bunch of other free books. I have currently downloaded books about iTunes, Mac, Twitter, Productivity, Internet Searching and WordPress. If I’ll find some of these worth recommending in particular, I’ll put up another post here with more details about it.
