Is there a specific protocol for hosting a "Welcome to the Mansion" party when someone rolls over 10k?

The other day, someone told me that it was a Fluther-ite’s turn to hit 10k and that person asked me if I wanted to “host the party.” I checked the meta section to make sure nobody else asked the question first, and since it was not posted yet, I wrote it out and posted it. It got modded for being a duplicate. I am 100% sure it was not written when I asked it. When I discussed it later with the person who told me to write it, I determined that according to the time I wrote it and the time of the question that was kept, mine was definitely first.

I don’t usually get involved in Fluther stuff because I’m not on the site all the time. I did feel bad, if I stepped on some toes by asking the question, if the job is supposed to go to Fluther insiders.

Just for the future, is there a certain protocol for who gets to “host the party” and how it’s done?
