good question how do I find the time?
Well I initially spent a lot of time on the Zynga forums reading up on all the tips and looking at the charts that people linked to for maximum profit/xp in shortest space of time.
Now I occasionaly get DS1 to harvest and plow for me (but I do most of it)
Basically I just don't have a life - and the last 3 weeks since SS have said I shouldn't leave DH in sole charge of the DS's at the moment I've hardly been out so plenty of time for clicking on the computer with DS3 snuggled on my knee
