Welcome to CM and this group! Yes that is a good thing! It means someone is bumping your post to the top so that it will get more views and hopefully more responses. If you go to the FAQs section on your main CM page you can find a page with all the abbreviations used. I would give a link, but am mobile and cant paste on here.
Ah, don't feel too bad. Many of us had to learn what these abbreviations mean. And they are still coming up with new ones almost daily! If you aten't too sure what something means, jyst ask and someone will be glad to help out.
