Hi God, agreed on the spending philosophy, Grin aims to be digital cash/money primarilly (or at least, that is what I envision for Grin).
As you can see in my post from today we just have the Grin Community Council website online:
http://www.grincc.mw
It contains all kind of information and we are looking to add information on exchanges, miner retailers and yes absolutely we should also mention places where you can spend grin. Some like slate-pack market are listed on
https://www.grincc.mw/hub
but I think there might be a few more. If anyone knows other places that accept Grin, let us know we can list you there and maybe make an official page for it on the GrinCC.MW website.
