I think you meant "although."
With that said, I think it is best not to be picky about someones grammar and punctuation on a site like this. EVERYONE makes spelling, grammar and punctuation mistakes. Additionally, you never truly know the educational background of the person typing. They may be more highly educated than you would presume.
Case in point, I have many friends from Stanford who are obviously highly educated, and yet I often get texts messages from them with many spelling mistakes. Really who cares. In contrast, I know another person, who has never completed high school, yet she is the first to point out my spelling mistakes in text messages. I mean really, who gives a sh*t, it is a text message for heavens sake, and I text using one hand most of the time.
Why don't we all just agree that this is a casual forum, and many people don't pay attention to grammar, nor is it really expected, especially when many times people make quick posts without proof reading.
Unless the person is clearly typing in ebonics, then nobody should point out spelling errors, or state someone has poor reading comprehension. Never make assumptions, you might just be surprised at the high educational background of the person you are trying to insult.
