The GNU Image Manipulation Program (GIMP) is one of the most powerful free graphics applications around. It is a great alternative to the legendary Photoshop from Adobe and other closed source graphics suite. However, one of the greatest challenges facing the GIMP is a lack of clear cut tutorials especially for beginners.
There are some really great GIMP text books out there but most of them in my view, are targeted more to those familiar with it than newbies. The following 3 sites have great user submitted GIMP tutorials that are sure to meet the needs of both beginners and advanced users.
This site is neatly laid out for easy navigation through the tutorials. You can favorite a tutorial, subscribe to their RSS to be informed of new tutorials and also share any tutorial you like with friends on the various social networks.
Similar to Gimpology, this site also features an impressive list of user submitted tutorials from users of GIMP.
This site features video tutorials for those who love to learn through audio-visuals.
These are three of my personal GIMP picks for GIMP tutorials especially for beginners. If you know of any, just let me know and I will add them.
