Hey there guys, I would like to remind you all that the site does have a spell correcting system. In order to get it to work, all you need to do is to launch the HTML editor and the option of spell checking / correcting will be unlocked.
Beyond that, there are other ways to spell check and then correct public contributions. For example, a very known thing is advanced internet browsers that auto correct which I find incredibly useful.
Besides that if people really want to keep publishing perfect contributions, they can delete what they published and correct their mistakes later... Secondly, there is an option to edit spells and articles by the member who posted it.
Beyond that I agree with Murife, we all make mistakes, and it is very unfriendly to call people who occasionally make mistakes "uneducated".
