I was very excited when, thanks to this thread, I started looking into PostBox. I was so pleased with a few of its features that I went ahead and bought it after just a few hours of trying it out. Duh. I never learn. A few hours later, I found I couldn't get a couple of things to work, and that's when I found out that PostBox can't be bothered offering tech support. They've put up some "trouble-shooting" advice, and if that doesn't work, well, too bad for you. Or rather, too bad for me. [BUT SEE BELOW]
Addendum: Ah, me of little faith. This morning I was going through some of the PostBox Help information, and to my surprise, I saw a link to a form I could use if I still hadn't found what I was looking for. So apparently there IS some possibility of real tech support after all. Not sure why I didn't see it earlier--perhaps because I was signed in this time and not before? Oh well.... I should add that I'm still finding features that I like about PostBox and am once again happy to have bought it. (If I could find a way to delete my earlier grumbling, I would, but since I can't find how to do that, I'll just "modify.")
