Just wondering if some of the Achievements could be revamped...
The AWA hours ones need a progress bar like some of the others.
A couple more steps up the "border" ladder would be great, to bring it into line with others, as it stops at 25 used/4 steps. Plus, given the number of borders free with a new account, drop the 5-border step altogether.
As well as the 28-day one, the Streak achievement could reward a week, 50 days, 100 days and a year. Pop a counter somewhere to show number of days in the current streak.
