I'm going to be implementing tagging soon via http://knpbundles.com/FabienPennequin/FPNTagBundle. This system will allow users to tag themselves and other content (much the way you see it done all over the internet these days).
I am wondering if anyone knows any good methods to reduce misspellings in tags? O should I simply allow them to exist because they will naturally filter out?
Edit: I'm curious why the downvote, I have already searched Google and SO, no one has addressed misspellings in a system like this. How is this not a valid question?
