hi guys, i have this problem. i have a script which adds a user to a DB, but before the user can be added, the user has to go to a seperate site, create account there, and come back to my script page and sign up with me. the idea is i need them to have the same names in both the sites. is there any way to automate the process,

for example if someone with the user name 'jack' comes to signup in my site i need to check if the user name 'jack' exists in the DB.. over in the other site and if it doesnt add the user jack to both the sites, with practically the same information. the second site actually is an MSN group, so i do not have DB acess there. so the only way go aobut is, internally navigate to the MSN group sign up page, and sign up the user,and catch the error messeges if there are any, or else add the user to both the sites. i know there is some HTTP navigation stuff out there, but is what im trying to do possiblle?
