P2P chat for buying, selling Grin

In my observation, it was unilaterally decided to create a p2p chat for placing orders for the purchase and sale of Grin coins.
Grin_P2P (EN)
Grin_P2P (RU)

The buyer places for what currency, crypt, bank and price he wants to buy the coin, the seller places how much Grin and for what currency, crypt, bank and price he wants to sell. Either the buyer, the seller selects an existing order in the chat.
Transactions go through a guarantor with a commission of 1% but not exceeding a commission of 1 Grin per transaction, regardless of the amount of Grin

The guarantee is 100% responsible for the security of the transaction
