I needed some break from work on backends, so today I launched multilanguage support for website. Not all texts are currently translated, especially some emails, but I'll fix it during the time. Currently English, German, Russian and Czech translations are available. If you want pool site in your language and you want help me with it, let me know :-). I'm especially looking for some French or Spanish native speaker...
1: Can a date/time localization be added?
Yes, it's already on my list. However it will come after DGM.
2: In the statistics page, can an additional field be populated showing the number of shares submitted for past blocks?
Yes, this is part of DGM update which is planned in next days.
