I'm so sorry to hear this Linda, but you're doing the right thing for you and I don't know how you've continued for so long with all that you're doing IRL!
This is a bit of a tough board, I thought about stepping back up to cover the gap once I've finished work, but I stepped down because I'd literally run out of topic inspirations and that's what's hard. I agree, a new perspective is needed here and I'm excited to see who applies.
In the meantime I will be around the board more after July 24th (apart from when I'm in hospital having this baby).
