Nora: I agree! There should be a separate site wherever, where just cloud formations, sky vistas are presented. No reason why the Photography forum administrators could not set up same, if time allows! I mean, we have great forums for almost every individual plant species there is, and on and on, but no opportunity in the Photography forum, to zero in on specific subjects, other than photography skills-important as that may be!! Who doesn't look at the sky daily? Someone with Gard.org expertise could advise you on how to start a thread with your desires in mind. Cheers!
