I saw these this week...I'm convinced that people don't see the differences in it's/its and your/you're.

1. On a national jeweler's website, there's a link to "A Quick Guide for Each Month and It's Birthstone." (At least they got the singular/plural thing right.)

2. I saw this in an email. "Okay, let me know when your in this morning."

3. I received this in another email. "My two arn't done yet."

4. In a pamphlet from a genealogy source, I read, "with their wonderful cemetary records." The same document had, "help the region regain it's place."

5. On a site with lots of resources, there was a "Teachers Link."
