Sorry if this is dumb, I just woke up and had this idea randomly. What would happen if the site had a built-in mechanic for correction spelling mistakes. It could be opt-in (or opt-out?) if you don't want anyone to bother you. This would allow other people that notice them to ping a comment author privately with perhaps a short message explanation.

Not everyone has English as their first language which is why I think it could be valuable. If the feature is not built into the site, correcting someone would be seen as a negative experience (I think) both in public or private messages.

It would be up to the comment author to edit their comment. (Or perhaps a way to accept the changes would be nice?)

Thoughts? Is this a thing anywhere else?

Edit: I put feature request in the title, but this is more of a discussion of the idea in general. I don't expect this to become a thing, but I feel like it's interesting to think about.

In ~comp, there's a post about optimizing a string parser, and one of the tags is "optimisation" instead of "optimization". This makes me curious, what's the official policy for regional spelling differences in tags? Will people be encouraged to use exclusively American or British spellings, or will the search feature (when it arrives) automatically link results for both if you search for either?
