No problem. There are a set number of communities right now in the explore communities list and some like mine occasionally pop in and out of the queued list. Apparently being displayed is based on active posting and a few other factors and the list updates a few times a day.
My fault really for not promoting the community as much as I should right now. There's a technical problem initializing scotbot for the steemianpolitics tribe but hopefully tomorrow I can fill out the settings and the tribe will be in full force rewarding political content.
