Well in order to get a "rank" or "reputation" on this site, you must show your knowledge within the "Forums" and "Chat". If you are apart of a coven and in "Council" position, then you can also show your knowledge in the "Articles" and "Spells".
Now remember having a rank is not a right, it's a priveldge (sorry if spelled wrong), the best way to keep it is by, giving your opinion when your right, and accepting constructive critizism if your wrong, and learn from that.
Well that is my thought on how to get a reputation on this site. :)
