Yeah, don't see most authors having a problem with being told, so long as it's polite. Can't see you having a problem there, Trenna.
Sometimes if it's the odd one that caught my eye while reading I'll include it in a comments folder. But if it's more than a few, I'd probably prefer to do by email. If only for the fact that I just think that it's kind of a boring thing to put in a comments folder. I always feel it's more nuts and bolts stuff, you know? Relevent and important to the author, but not necessarily interesting for the majority of readers.
But certainly, at a personal level, I don't mind how anyone tells me, so long as they do and I get to fix it, rather than spotting it six years later and banging my head on the keyboard.
