Thanks Thomas,
I don't feel it's a burden at all. Like your post to me, I can choose to reply or not. In this case I wanted to so I can explain it's not a problem.
Where I get caught up is, if I don't reply at the time. Had I passed on by and decided to reply later, then it can take some time. Sometimes just to find the post is an adventure. It's all good, I learn something new every day.
Something I think I just learned, is save the e-mail that said a certain person replied to my post. By doing that, I know I still need to reply. Trust me I don't reply to every post, nor do I feel the need to do such. In your case I made an exception.
