I was trying to get the Key to the Wiki achievement which means I should contribute to the wiki for 5 days straight. Now, I'm sure I didnt miss a single day but then I got a reset. I'm back to day 1/5 again. Perhaps I am using the wrong time zone? Where can I change it and what should I change? Thanks for answering.
@Knapy1997: You have to make one edit every 24 hours to keep the Achievement active. Best way to do this is to set up your alarm clock at a time when you're comfortable with going online, then make an edit at that time every day.
I didn't mean exact same time, it's just that you have to make sure you edit something within 24 hours since your last edit. Be noticed, it has to be an article edit, NOT forum post or uploading images/photos. Check your Contribution tab for more details.
