let me say my idea;

we know that we can phpnukes password property..

and so we put these codes;

1)in to phpnuke's user reg form;

firstly connect the both phpnukes db and vBs db to check if the user exist; if not;

connect to phpnukes db to add new user and then connect the vb's db to make new user..

2)in to vB's user reg form

same as at phpnuke...

i think this will work...

any idea?
