Changes are inevitable. I've been reading a lot of threads about the new changes, and some people are seriously freaking out about it. I feel like it's not that big a deal... but when we all start reading threads and read one person freaking out, we all start to freak out a little. I can't imagine it being such a huge change that it would literally tank someone's once successful businesss... but then again my shop is relatively new here. I try not to get too upset over feedback in general. Some people are going to leave negative feedback no matter how many hoops you jump through for them.
All you can do as a seller is to roll with the punches and adapt, and keep providing excellent customer service. Running a small business is no easy feat, we all wear many hats: designers, photographers, managers, customer service rep, etc... we have enough on our plates to worry about already! Eventually they will replace this system with an even newer, more annoying system, just as soon as we work out the kinks and get used to this one ; ) Just remember... "this too, shall pass."
