Is there a way for premium members to increase the allowed prim count on their land? I would like to put some things there but the total prim count is nearly 300 prims. Is there something I can do to increase past the 117 allowed?

I've been invited to join a group. I received a message. I click on it and it shows the invite. I double click that and I get the join/decline panel. I click "join" but the group doesn't show up in my group list on my profile. Is there some setting on my account that I need to fix to allow joining the group? Or is that something that the group owner needs to fix?
