I know I already emailed these, but for the sake of keeping them in one sensible place, I'll copy and paste here:
A couple of small things that always bugged me about Memrise that you might consider fixing/implementing, at some point in the future maybe?
1) Accents. The way Memrise seemed to work was that if you skipped accents completely in a sentence, it marked it correct. Or if you put all the accents in, it marked it correct. However, if you put one accent in and missed another one, it marked it wrong. It seems a bit harsh when if you'd left them out completely that would be acceptable. Perhaps a Duolingo-esque warning about missing accents would be better? Same sort of thing for hyphenation? Maybe make it an option?
2) Spelling forgiveness. It's rather frustrating when you get a sentence perfectly correct with all the grammar and then misspelling a name in the middle of it all, and having it marked incorrect. What do you think about forgiving one or two spelling mistakes, with a warning perhaps, based on the length of the sentence? So if it's a short sentence forgive one, if it's longer forgive two, or something?
Anyway I know you've got lots to do, but you did ask. π
