Google Searching for Codeigniter User Guide

Me sharing this won't change anything, but I guess you'd like some insight ...

Sadly for us now, but shortly after I joined the team, EllisLab went through a kind of a re-branding process. It included bringing all of their products under the ellislab.com "umbrella" and have them use the same designs for web pages. In fact, that was one of the reasons for changing the docs.

Before that, as old-timers probably remember, CI was on its own domain. Nobody wanted to break the then "old" links and so codeigniter.com/user_guide/ redirected to ellislab.com/codeigniter/user-guide/, but unfortunately this redirect got broke on numerous occasions and for long time periods, so unfortunately Google indexing may've been affected by that.
Good thing I didn't merge this though.

It will sort itself out eventually, perhaps in a year or something like that.

The (obvious) idea for EllisLab to redirect back to us has been brought up before, but I'm not sure if Jim has been in contact with them on that matter. I guess he'd reply himself to shed more light on that one.
