I really appreciate the info that pops up when you click the "Like" button:
If a specific post was interesting or useful to you, we recommend that you Like that post. It tells the post author, and others, that you found the information valuable. Clicking Like is another way to let others know that you enjoy it without leaving a comment.
I've been promoting the idea of offering comments to build threads for YEARS, even if you are not so technically inclined to offer nuts-n-bolts input, just say you like what you see!
Thanx, Morgan, for this great forum.
