1. I just posted to newbie neighborhood but in the middle the post disappeared; I redid it but I don't know if it happened because I hit submit by accident and you got two, or what happenned. Who do you contact when a mistake like that happens just to let them know- like, for example, in this case, to discard the first and use the second if two topics show up by acident?
2. I see a lot of icons on the forum left side- pages, pages scrolling, question-mark overlay...where is the legend that explains what these symbols mean? (...and Yes, I do see the partial list at the bottom of the index page, thanks.)

. Not wanting to be a nudge; just legacy of doing research for 30 years.

Exactly. Thanks.
