To join people you can NOT take money for according to Eslam (islam). If you wont then you can take it after marriage not only to join them also in a from a gift only. To name a site a Moslem name but to an act of evil that go's against Allah rules is not acceptable. Lot of Moslem people do not know and by such sites are misleading them and making them do what Allah dose not allow. Hope all avoid such sites and some God fearing people provide decent help to whom need such help.
