[Plugin: Register Plus Redux] Date format

I’m having real dificulties because users are having trouble with the date picker because it is in a format they are not used to (mm/dd/yyyy )

in the UK it is always dd/mm/yy

Is there anyway of changing the order of this in the files. I know that register plus (the original) had settings for the date picker this would be good for this plugin.

If not just the coding would be great
