Well I never would have guest this day would come but today this little site is 10 years old, The site has come a long way from it’s beginning on the Fan-sites.org with our old URL of Katie-Cassidy.us to having that all be taken away and coming out with a new host and new URL well we have two of them now. I don’t no if people remember this but I am not the original owner of KCO I came on as a co-web and then owner after some time and why I can not remember who was the first owner I want to say a BIG THANK YOU to them as if not for them there would be no KCO today. We have gone on a long trip with Katie from TV shows Harper’s Island, Melrose Place, Gossip Girl, The New Girl and of course her big part in Arrow to her movies A Nightmare on Elm Street, Spin a.k.a You Are Here, Monte Carlo, Kill for Me, The Scribbler, The Wolves At The Door, Cover Versions and Grace we have cover them all and hope to keep on going in the years to come. I no this is getting a little long and sad but I would like to say to all of you who keep coming back to the site and have helped me in all these years with news, info, photos or just being here I want to say Thank you it dose mean the world to me and keeps me updating the site and a big thank you to Katie her self I have no clue if she knows about the site or not and I have never said to her but with out her there would be on site no matter if she knows it or not.

Bit of site update the layout was done by Cole Codes Fansites and the header was by the great Headers Online, And I have cleared out the Affiliates of all dead links so we are looking for lots of new ones for that.

Now it would not be a celebration with out some new things and I have three for you two will be in this update and 1 in the next. The two for here are some new movie stills from
The Scribbler
and Black Christmas unfortunately I could not get them in HQ but they are still a great addition to the site
