1 Can I connect btcpayserver or do I need lnbits?

2 can I put my own personal relay for backup?

3 I seem to have done something real goofy and put the whole thing up on my GitHub/ domain when I really just want the customer facing page. How would I accomplish this without a redirect?

4 I hope you got my zaps. I tried sending but my client isn't showing them on your note.
