How Do I? Two Questions ...

I've been thinking about the Carnival of Central and Eastern European Genealogy lately, and I'm just wondering what I should do to improve it. Lately, I have been having difficulty getting enough submissions for each edition of the carnival. Does anyone know how I can increase the number of submissions for the carnival? Also, does anyone know how I can garner more attention for this carnival?

Any suggestions or advice is welcome and appreciated. Thanks!
