Please don't spam too much. I appreciate the effort, but this is at least the third announcement post. We don't see Ellesime post lost of announcement when restarting Diplomacy, do we?
As an alternative, you may consider asking admins or board masters to change bbs / board description to announce it.
Plus I think you need to give players some time to create their character. Unlike house campaign, you need to really really plan ahead, once created you can't say I don't like this can I change my class. And this takes time.
