I have been active on MemRise for years and I prefer to vary which course I learn on week by week, rather than keeping to one course. (I even like to keep to a subject [eg Volcanoes and Earthquakes] for a prolonged period, learning and revising on several different courses at the same time).
I finally reached 365 consecutive days of learning and was hoping for:
a) a 1 year medal (a bit like the daily goal [continuous days on a single course] is honoured) and
b) the counter to keep going, but a week later it is still showing 365 days. (Can it be that it doesn’t expect that loyalty or it can’t do the maths?!)
