Possible Deletions

So mine and live's world on our joint account crystal fantasia are not going so well. So i was thinking about deleting the following. Pandora's Rebirth because there's only three people on there anyways, Bleach: The next Generation, and Unfortunatly T.I.M.E Academy. maybe I could rework T.I.M.E. then try again but it has been dead for a while now and I don't see it starting back up. so what do you all think? Should I delete those worlds?

End
