i used a wordpress mu installed by a company called wordpressmudev and they put some codes in my wordpress mu, every page and every blog has a blogroll and a footer pointing to their site. how can i remove those hooks? i asked wordpressmudev and they just told me to sign up for their forum which i need to pay $79 a month so that i can post and discussion with other users. i don't have that kind of money to pay. so if someone can kindly instruct me i would be very grateful! thanks!
