I must agree with Marg and Sheila. A "LIKE" or "Thumbs Up" button would be great. Just so I don't have to scroll down through a bunch of "Good job" or "Nice work" or "I like that" posts to see if anyone has anything constructive or additional to add to someones work.
I am a firm believer in constructive criticism and maybe someone elses take on a given project or question but, I refuse to just add a post just to say "Good job thanks for sharing".
