I am doing a quick shoutout for First Site Guide, a site dedicated to providing help and guides on a variety of web development issues including web design, blogging, SEO, web marketing etc. As far as I can see, most (if not all?) of their info and online how-to guides are free. In particular, I want to point out their new Online How-to Guides section. It looks pretty good. The snapshot below shows but a portion of the free how-to guides they have on offer.
I have not had time to delve in any depth into each of the guides. But a quick look tells me that it might be worth bookmarking that page.
Enjoy! And please leave me a comment if you do use their guides, have used them, or have any other feedback you would like to share.
