I have long followed the Texas Photo Forum web site as this has been one great resource for photographers in Texas and in particular in the Houston area. A year or so ago, the site changed to Pixtus.com as the owner of the site, Able Longoria, merged his efforts in another state and expanded his site nation wide.
The pleasures I find visiting Pixtus.com in viewing works by others, submitting my own photos for review periodically, and obtaining information about areas of interest.
Recently, Able posted a Photography Cheat Sheet which I believe to be an excellent resource for those of us who want to improve our photography. Check it out! http://www.pixtus.com/forum/site-info/153508-pixtus-photography-cheat-sheet.html
