I will only join if you let RPaul answer the questions
Q&A session

Bilbo21 is not a member of this group and has boasted of his ability to do harm to this group (clearly as pathologically misguided revenge against me).
RPaulB would be as welcome to answer questions as anyone else. Of course his answers would be as subject to scientific scrutiny as those of anyone else.

The forums are open for discussion of all topics that have some connection to astronomy. Are you blaming those who post for the fact that others do not?

Perhaps this forum should be restarted. I have questions, & may be able to supply answers to some topics.
netsitechess suggested an astronomy Q&A session in the chat room. Interesting idea which might be worth trying if there is any interest.
Normally such a thing might involve a small number of selected authorities and a group of people asking questions, but I feel many people here might know things about different parts of astronomy, so it would be reasonable to allow people to answer where they have some knowledge to offer.
If there is enough interest in this, it will require a scheduled time at which people can arrive and enter the chat room. We would find out if there is sufficient interest.
