Roma are back in the top four after going unbeaten since the end of October.
In a blog on his website, Totti wrote: "Dear friends, thanks for having lived together with me the birth of this new official site.
"It has been an unforgettable month that has seen me return on the net with this wonderful adventure and many other emotions.
"The victory in the derby, the first place in the Europa League group, the climb up the League table all the way to fourth place and above all the signing of the contract that will tie me to Roma forever. Giallorosso for life."
