'Correcting' language problems has a number of problems:

• The person may be using jargon that we are unfamiliar with, and we incorrectly assume that it's just a typo or other mistake.
• The person may be using jargon which gives clues as to his/her background, which can give clues in how to best help them.
• The person may be using a polysemous word (multiple similar meanings), for which they are using a meaning of the word that the editor is not familiar with.
• How do we decide which is the 'correct' dialect of English to standardize on? This could fragment the community if people are forced to post in compartmentalized sections.
• What looks to be an error in grammar may actually be an error in understanding, which is necessary to solve the person's problem.
• ... etc.

... some monks can be offended by poor spelling and grammar ...

I'm not a fan of poor spelling. I actively loathe people who believe that 'ur' is an acceptable replacement for 'your' -- but not because they've made a mistake, because they're just lazy in typing an extra 2 characters.

If someone posts a completely horrendous message, there are plenty of polite ways to respond, such as 'I tried reading your message, but I have no idea what they're trying to say', or 'What did you mean by (x)?'. Or, just ignore it, and move on -- you're not obligated to read anything.

And to those who actually get 'offended' by poor grammar and spelling -- get a life! There are so many more important things to worry about.
