Dont make fun on other's post they are trying their best to write proper english or at least understandable especially if they're not a navite english speakers, instead of making fun on other try to understand what they want to deliver and help them, Actually after reading all replies your reply is the most non-sense I have read.

For the OP, Their edit history is not visible for us but I think admins can see it, though for me it is not to important to read the edit history post.

But if you are having personal problem's in a thread or an argument that the user violate's the rule and you want to keep an evidence use printscreen or screenshot's and save it if you want to report a user for an abuse.
