(How this goes is very simple. Mostly, mothers (or fathers) can announce the birth of their children. Cubs can announce themselves if you want. That is up to you. This whole Ceremony is optional, but might be kind of fun!
Post as much as you'd like; it's a very open ended rp that is geared more towards the children introducing themselves to the adults, and making friends in other clans that they won't see as often in their own clan.
Don't forget that the clans migrate often, so this is seen as a good chance to know those outside of their clan.)
