Check your inbox - SCEA's confirmed that a further wave of LittleBigPlanet invites are on the way out now, and plenty more are on the way.
"Several thousand invitations are in the process of being sent out today by email," said one of the game's developers on the US PS boards.
"If you do not receive an email from SCE today, you will also be able to sign up over the next five days on a variety of popular gaming sites. I cannot name the sites here, however the LittleBigPlanet News Site will be giving out more details tomorrow.
"If any further places to sign up are made available I'll update this thread again."
Eurogamer issued the first bunch of invites last night. Loads more through the link on how to get involved if you missed it.
