i had trouble adding them as an addon domain, i dont see them on my addon domain but they appear on the dropbox on the subdomain, but they do not appear on the domain tables..
my problem is similar to his http://x10hosting.com/forums/free-hosting/149200-addon-domain-error.html

teamasap.info
teamasap.co.cc
