Ah there we go I see you now!
Some quite glossary stuff lol:
#Nostrich - that I think is us so adopters of Nostr
#PV - is like our gm on twitter
#plebchain - is like our followfriday but itβs every day
#zap or you might see this β‘οΈ- is to send SATs to each other
Cant think of anymore but if there are will share lol
Also if you want to test sending an invoice - create one using wallet of Satoshi and can send it as a response 1000 and can send you some SATs
