want to ask about the bitvault invites,,, how it work there and when?
Is there is a specific rule to get them or what ?

Members will get 1 invite if they reach "Bv Fan(atic)" userclass (requirements: Must have been be a member for at least 12 weeks, have uploaded at least 500GB and have a ratio at or above 1.3) they will receive 1 invite when they reach "Bv Superseeder" too (requirements: Must have been be a member for at least 16 weeks, have uploaded at least 750GB and have a ratio at or above 1.4) and they will get 2 invites for the rank "Bv Legend" (requirements: Must have been be a member for at least 20 weeks, have uploaded at least 1TB and have a ratio at or above 1.5).
So only 4 invites / account allowed as I know.
