Open questions to all person on steemit platform.

Hello Steemians,

1. What is this HF20?

2. How to handle this judicially ?

There are so many questions which are irritating to us at least so many minnows like me. Is there any post or FAQ where we will get our queries, to satisfy curiosity, so that we can again work normally.

  I would like to request  seniors like @chbartist @stellabelle or team steem or so called whales, please please make a post where we get our queries in one post.
