Is anyone using the plugin that lets customers track their USPS shipping right on the website? Written by MPrough? It doesn't have a support thread and I can't find any earlier posts about it. I'd like to add it but I don't have time now to deal with problems. If it works right out of the box without a lot of code tweaking, then I can use it. I don't mind doing configuration but I don't have time for anything more than that.
