Message for attention of the PrintShrimp team.
Very interestingly, I've only recently started using underscores (_) in my SKUs in Etsy, despite using them incessantly in other aspects of life. However, PrintShrimp SKUs don't accept them. It's a very standard character. Is there any possibility of this being changed? It's reassuring to see that when I substituted underscores for hyphens, the order import system is intelligent enough to convert them, but I still see this as being a surprising workflow issue in the future.
