I flagged an OP’s post last night because he typed “i” instead of “I.”

This morning I woke up and the question was heavily modded, but the thing I flagged, with the “i” was left up. It has “i” in it more than once. I know I flagged it because I just tried to flag it again and could not.

I am confused, as this was never allowed on Fluther before. Is using “i” for “I” ok now?
