To edit your www.cc.gatech.edu/~<username> page, you first need to login to a server that uses CoC credentials to which you have been granted access. All on campus CoC graduate students are granted access to the General-Access Research Computing Servers upon account creation. After SSH'ing in, users should arrive in their home directory. Within that home directory, there should be a www symlink. Users should SCP the files in there. For those unfamiliar with SSH and SCP, we have a guide which can be found here: Secure Shell (SSH) Tutorial.
