all greek advisor question

[Energizer420]

I think I may have an issue with our greek advisor and im not sure what to do about it. See the issue is, is that a new chapter has come onto our campus and this happens to be the same chapter that our greek advisor belonged to at a different school. It seems that she just lets them slide by all the rules of panhel basically. Starting with last semster when they had first became a colony they were allowed to participate in greek week then during rush this year they were not able to participate in rush because they were a colony and had there own "special type of recruitment but they were allowed to come to our bid day. Now i dont want everyone to get me wrong this is not about the chapter this about the greek advisor. This colony is walking around saying that there participating in formal rush next semster but have not been voted nor even brought up to panhel and I know cause i go every week. Its not just these few incidents its a bunch more then that but what am I supposed to do because its just not fair that we have to follow rules and this new colony doesnt. Someone please tell me what should be done?
