I guess there is no established method of reporting these sorts of technical glitches, but if I noticed something wrong, I'd probably post to Editor Requests and /msg the author in the chatterbox if I found it appropriate. I don't think there's a need to warn the author for his/her spelling mistakes... God knows that if everyone were to /msg me whenever I screwed up my spelling or grammar I'd be in a world flooded by /msgs. :)
