Hi, sometimes I think there's no point in such groups also. Although the reason why they make such groups is they feel its easier to get more numbers that way, instead of having to ask each person individually which can get annoying. Then if there's any friends numbers they don't have it gives them a chance to get those numbers. Although lots of times these groups are public and anyone can see all the numbers of the people on the wall which I think is very foolish.
