^Now, imagine half a million messages like these going into the Internet every third of an hour.
^In perspective to that, you're doing just fine. (But yes, your English is deteriorating. Should you wish to keep it, please take a multilingual job. Should you wish to not continue your English, please work in your respective area.)
Also, while the site is more inclined to stick to Oxford US diction as the most formal of writings, we condone UK spelling and non-Oxford as well. Grammar preferences, on the other hand, may vary.
