And you are asking 1 of 2 things, or both to get HSL another 10%.
You would either want RG to dilute his ownership, which is he is absolutely not going to do, or you want supporters donations from HSL to be used to give to other small shareholders instead of going to the club.
There's little evidence that small shareholders want to give or sell anymore of their shares away. People like having their shares in Hibs and they are all going to be just as protective of Hibs as HSL.
I'm amazed that anyone would think that getting an HSL director on to the board is worth all of the HSL money for the foreseeable future going into the hands of other supporters instead of to the club.
We shouldn't forget that shares through HSL were available for a long time before RG came along and there was very little appetite.
