Can anybody says if Dafont is working for upload fonts???
I can't upload my new fonts...

Your latest submission was reviewed but unfortunately it had too many issues so we didn't select it. It didn't have kerning which was necessary. It also had an metrics issues (ascender/descender not set correctly) and the design was generally inconsistent. You can of course submit your font again if you fix these issues and it will be reviewed again if you do.
