Make sure to include as much data as possible if you want help. If you for example have issues with a streak. Tell us on which date it's broken and which caches you have logged on that date.
Sadly not all mails are answered within the timeframe they deserve anymore, there just are too many support mails and we can't keep up. But everything is read and we try our best to prioritize. Remember that Project-GC is a small project with only one full-time employee.
The support crew mainly understands two languages, English and Swedish, but we also have some understanding for German. It's really preferred that you write in one of those. If you can't, rather write in your native language than use Google Translate.
