Hello team, I recently launched a site called FinTastic BEacon for reviews of book/article related to business and economy (https://fintasticbeacon.wixsite.com/home). I have added wix forum for additional participation from members. 1-I want the members to be able post under any existing thread/discussion but i want the power of starting a new discussion to stay only with admins only. 2- I want to pin some of the discussion at the top e.g. intro or rules/model behavior while posting. Can anyone help me out with this? Thanks in advance.
