Thanks for reply.
I don't find "rule section in discord" where can I find?
When you look at the monitor, on the left side you have a long menu.
Under the Airdrop section, you have a rules section.
Click on the rules section and you can read it there.
My discord sometimes not showing all the sections.
Maybe he can't see the rules section.
In that case, installing the app could help I think.
