the comps subscription was good when i was in management, but a lot didn't like the fact it was done via vm (although i did send them via pm if people specifically asked me to). other people who weren't subscribed saw the vms too and i had people entering comps because they saw it being advertised on x's page. i don't think anyone really did it properly after i resigned, though. when they did it was the odd one and then they wouldn't do another for like a week.
along with that there were cnbs done every night advertising the the comp that had currently gone out and the comp that was ending in less than 24 hours (although towards the end we did it every two days because the way comps were moved out were changed, i can't really remember)
when i was last in management with mike he posted comps onto the habbo forum too and made it so they can enter either via the forum or on-client, although i don't remember how that went so you'd have to ask him
it's all about advertising, really. i focused most of my attention on new people, so i'd advertise in the welcome forum (and kept getting -repped for it which was rly rude :() and in my events since i was an eo too. although you don't need to be an eo to go to events and advertise it.
i remember @
hayden; and i advertising lit everywhere for an entire month and it went from 150 entries within a month to over 800 so advertise like mad~
