Jerry, as I recall you had a similar question last year. Through last year, when invoicing affiliate memberships and sponsorships in November/December, I charged the invoices to the usual revenue accounts. I then (as always) reclassed the billings to deferred revenues on the balance sheet. For YE 2017, I reclassed $44.3K of conference sponsorships and $35.0K affiliate membership. This year, I did things differently. They are now being charged as deferred revenue when the funds are collected. The attached PL through 12/2018 shows a slightly different picture for comparative purposes..
