Folks, one of the joys of photography is that it can bee enjoyed at many levels. Everyone starts somewhere.
The gallery is meant to be a "riskless" place to see your photo on the internet, and show it to others.
There is a reason it is structured that way, it encourages people to post regardless of their skill level.
These folks are not looking for your criticism, even if it is well intentioned. They just want to post pictures they are proud of.
There are lots of other places where criticism IS allowed , here and other places.
Having one place free from criticism, where people can feel safe is a very good idea.
Also, try to remember the audience....... This is not some high stakes gallery, I is a cordial meeting place for mostly older photographers to share and talk about Photography. All skill levels are welcome, and we do have lots of accomplished photographers as well as those who just do it for enjoyment.
Unsolicited criticism is generally not welcome anywhere, even if it is meant to be helpful
That should be a pretty easy concept to understand.
Be happy, take Pictures
