Please, can someone tell me how to make a new request for a ZNC while I have done the error of making duplicate requests, since my connection fell out the other day?
When you request, you don't need to be online all the time in order to staff see your request because every request is logged and user doesn't need to be online all time in order for request to stay.
You can request and leave (but in this case you will be rejected for sure ). You might wanna read this: viewtopic.php?f=57&t=1316
