@Paul: You should find a red button "edit" next to your comment (on the right side). You can click the button and then choose "delete comment". For now I deleted your double comment.
Thanks. I noticed that there's a "THANKS" shortcut already installed on this forum. How is this used? Is it enough for me to click on it instead of replying this way -- if so, I have never come across this feature on any other forums and it's great!
Would suggest less white space. Perhaps consolidate yellow video icon on question line; same with comment info.It helps me to be able to scan more questions per visible portion of the screen. Thanks.
