Some things on the forum like hidden mail address arealready some addressed privacy concerns by default, repeated merit, activity and se forum functions that continues to get a repeated answer could be explained by a default welcome note or possibly with links to where newbies would get clarification other than having them start there own episode.
There are some suggestions but implementation relies in @theymos hands and we have seen one updation after many years which is adding @OP to the thread creator name so these others will possibly take more time to be implemented correctly.
These welcome notes could help newbies as well save forum from lot of spam threads that ask about rules and merit related stats because they tend to ignore the forum search function and their direct approach is to ask by creating a thread but will see if have it along with new forum software or not.
