As Lantz has said before, he can't actually edit the sheet, it gives him an error. He needs to tell one of us to do it.
But, in terms of when he should do it by, that is entirely up to Elf to decide. He said he is busy for the next week, though, and probably won't even have time to get an RP post done (which is more important, because not posting in the RP holds everyone else up), so I wouldn't expect it before then.
