Remembering an old thread, a linden said it was possible gift premium membership.
It might be easier for my main to open a support ticket and do that instead. . . but that requires asking people for things
I would like to sell linden so I can upgrade my account to premium, but my "LindeX trading limits" are 100USD buy, 0USD sell. My main account has substantially higher limits.
I just recently added payment info, if that's relevant.
