Another 180+10 days question about MDE

[buzzgirls&dad]

Shortly we will need to make our 10 days of ressies and I haven't made any since last year really pre MDE. Last year everyone was making them on the British site. Any who....If all works correctly If I sign into the MDE site and make sure my room ressie shows up is there anything else I need to do to make my 10 days of ressies. Do I need to add my room ressie in anywhere else so I'm able to make all my ressies. Please advise my on anything else I might need. TIA
