hi everyone.. ive tried to wrap my head around this for awhile but cant seem to get it perfect but for some stupid reason you can do this on a windows ftpd's easily for some reason.. here is what im trying to do:

2 ftp users

admin and guest
admin = /var/pub/ftp/admin
guest = /var/pub/ftp/admin/guest

guest is locked its home dir so it logs in and see's just /

1] what i need is guest to be able to create directories and write, but -not- delete .. realistically if they can just not delete any other users ie admins files in his home directory it would be gravy, but i want them to be able to read any file

2] admin to be read/write/delete all he wants

any help is greatly appreciated

Not 100% sure but you can take help of sticky bit here. And making admin as the directory owner he can perform all operations.

The "sticky" bit prevents renaming or deleting a file unless you own it. It's commonly used for the /tmp directory.

If your Linux supports access control lists (ACLs), then you can go much farther. (This is basically how Windows does it.) ACLs provide very fine-grained control for file and directory access.
