Aopirose was quoting WhiteDaisy and what WhiteDaisy was describing is "Guaranteed Placement". Some schools guarantee that if you go through the recruitment process and fill out your bid card the way you are supposed to for each round, that you will receive a bid to a sorority at the end. This is legal, although I don't know any schools that use this process so I am not certain how common a practice it is. It does not take away a sorority's right to select their members. It also does not guarantee that a potential member will not be cut from all groups or that she will get her first choice. All it does is guarantee that if you are still attending parties up until the end of recruitment and you stay with the process, you will receive a bid from one of the groups who's pref party you attended.
That is not the same as "Bid Promising" which is when a sorority member tells a potential member that they will get a bid at some point in the future.
ChiDeltJen - bid promising is against NPC rules. Since you are a local, you can do whatever your rules dictate. If you are going by NPC rules, however, it is a no no.
