That sounds more like a problem on your end with communication with one of your members who contacted a company, gets sponsorship and then tells none of your admins about it.
As far as not having time to posts your builds here that's fine. I just found it odd that one of your Admins would come here and start a thread in the Golf Cart Events section of the forum and post a link to your Facebook group with no intentions of coming back here. I call that a spammer.
Have a nice day and good luck with your contest.
