I've recently used gforms on a german site and I realized that the subtext on the preset inputs (like the name field has "firstname" and "lastname" etc) can't be changed and thus renders that field somewhat unusable on a site that isn't in English...
Currently I've had to use jQuery
...which does the trick, but is a bit tiresome with bigger forms :P
Could you include in future versions, the ability to
a) have a page where you can choose the language of the site and then if language-X is chosen, then those kinds of preset text are in that language
b) make those fields editable for us to change as/when we need to...
