If your site is on "free hosting UCOZ".
How to remove a banner advertising UCOZ of runners with their site, this issue arises in everyone who uses a service (ucoz.ru, at.ua, clan.su, moy.su, etc) can be disabled for $ 3 per month paying ucoz. I offer you a small code for $ 0.35 which will hide this annoying banner on your site forever!
If you are using your site for its "iframe" - refrain from this kind of scripts.
After installing the code, you can stay a little icon in the upper right corner, "to create a website." But the main listing, and Begun by Ucoz disappear !.
