giving invites means we frame rules like :
if a user is banned for low ratio the one giving invites loses all his invites...this is rude for him who is a reputed member.
A modification can be made to above method as :-
-> after the guest gets usual account reset his ratio
-> he is allowed to have a maximum of 5 gb difference between upload and download
ie (download- upload)<=5gb
-> if he fails to fulfill above condition his account is deleted
-> even in that case dct will have extra 15 gb upload
-> continuing this way if he uploads 50 gb the max diff of 5 gb condition is removed from him
and his account is normal
-> mods please think over it it can really help to attract members who really need a account and want to continue with it but cannot get the invite.

thanks
