A further introduction into the various systems (i.e. trust, activity, merit, ranks) are relevant only after this.
I wouldn't mention things like trust, DT, the different type of flags, and things like that at all. That will just confuse newbies and maybe have them look for alternative sites to discuss bitcoin and crypto. For ordinary members, doing any changes with the default trust setup is something most never even do.
That's my point: the bottom line is that Newbies should be introduced to the rules of the forum.
Anything that is related to business or transactions should be dealt separately once the user is integrated into the SMF system. By placing guides to certain difficult forum concepts when they most prominently arise: maximum post error page linking to the h+c rank guide, an actual link to the forum rules when you get a post deleted by a moderator, a confirmation warning when clicking on Newbie/flagged-user links, etc.
