And sometimes I think the group owner is too greedy. Now the group is already full and new members cannot join this group. I persuade he to upgrade the group to 500-members-group. But he always wants QQ-SVIP to build a 2000-members-group and doesn't want to upgrade to 500-members-group. Now there are just 360 members in this group. 500-members-group is already enough. (The group owner is a foreigner)

Now I know it is not because he is too greedy, it's only because he uses the old version of qq and cannot find the upgrade option
