I don't know how hard it would be to add some kind of spell checker to parse a submission each time there is a new article, but it might be interesting: the basic framework is already there, since it is possible to edit and re-edit your article to make it "look good", usually by changing the HTML tags.

So... If there is such a parser, I think it should not be too hard to show the words that might have errors by painting them in red (I am thinking that this should be something that only the author should be able to see, so maybe that it should be a new tag like <GRAM></GRAM>.

Well, this is just an idea. I do think that grammar is important but it does not make things "unreadable". It just makes it look more perfect, which is something to consider because Monks are seeking/showing the "Truth" in their contributions.
