This forum did a great job before introducing the “critique request†button, so why changing the rules when it went wrong one time?
I’m also convinced, that the less helping critique there is, the more boring this forum will be.
Personally, I don't see a problem with the critique button.
You make some interesting points Arnaud, but as Andrew said, it's common courtesy not to offer critique unless we know it's welcomed by the person who posted the photo. Some engravers want critique and advice and some do not.
Right now there are three options: 1.) The critique button when starting a new thread. 2.) Asking for critique when posting a photo of your work, and 3.) putting C&C WELCOME in your signature, subject line, or in a post.
Whoever uploads a photo to the forum as 100% control over whether or not they receive critique.
