The way I think of it I have to configure proftpd.conf (or some other conf file) so that when I connect with ftp:
1) Give the username nobody and password passwd1 and connect to default xampp folder (ftp://localhost
2) Give the username sotos and password passwd2 and connect to my public_html folder (ftp://localhost/~sotos
Any help on how can I do this? Thank you..
