I've looked but I don't see a way (at present) of changing the default site colours from light grey text on dark grey background.
Don't want to sound like a whinger but that combination is difficult to read -- especially for dinosaurs like me ( and no, I can't hear your cell phone either as oldies don't get those high frequencies like the kids can hear LOL)
So, is there a way of implementing a more eye-friendly colour choice for those who want (need) it?
