I'll have to get back on in a bit. I honestly don't even fully understand what the hell Metamask does. I only know that when I was on the myetherwallet site and wanted to access my wallet, it told me I'd need to do so through a number of options, and I chose that one, which installed a plugin which requires a password itself in order to access and then send or receive.
What I didn't understand about this interface is that you have to Add Tokens manually... As if it doesn't know what anything is until you set that type of crypto into it, and then upon doing so, as a test I sent to my wallet address some POWR from my Binance account. It worked (at a horrible cost) but then once it's in there, I see only an option to send Ether out of my Ether Wallet, but don't see any ability to send out other forms of currency (such as Power Ledger).
