I'm a new user and noticed a bug when posting a problem of mine on Stack Overflow.
If you have less than 10 points (or whatever it was called) it says you can't post any urls. As I really wanted to use the urls as demonstration I thought I'd remove a "t" from "http".
So instead of posting this: http://www.website.com/, I posted this: htp://www.website.com/
When then looking at my question I asked I noticed the urls was working and actually transformed to urls with "http" instead of "htp" which I originally typed in. Why? Well, I think at the moment you are auto-correcting bad url inputs or something like that.
