Why does PD have only English as languages options? PD is expanding, why not add popular languages like Chinese, Russian?
Translating the whole site would probably be quite costly and most people would understand most of the english words and google translate is your friend. Furthermore, I don't think devs have lots of time to attempt to redesign the whole site to suit the languages.
I dont think that redesigning some of the elements would be hard since they should already have it and they will just change the strings.
About the text in general its just strings where you need to add a translation and create locals. Again not that difficult, just needs some time.
If they'd offer me 0.08 for the Dutch translation, I'd do it without a hassle and I think multiple others will do too. Only thing that matters is if their priorities are set to the translation.
