I am so sorry to ask a stupid question. I have looked everywhere and can't see to see any mention of the things that look like an envelope in the first column of a post. Some just look like letter, some look like there is light or a flame coming out of the time. And, a post that I made looked like a letter with a black dot where the envelope seals. I just want to make sure that I'm not doing something wrong since I seem to be the only letter with that has the black dot on the envelope. Thanks for any help or advice.
