pkg_mgr, ntfs_3g, sudo, partition access.

[Mohammad BadieZadegan]

Hi everybody,
I have installed OpenBSD5.9 on my HDD last partition successfully.
I have 3 questions about this latest release after reading the OpenBSD FAQ
page,
1. How can I install pkg_mgr, sudo, as older releases?
2. I installed ntfs_3g but still I can not write over ntfs flash usb! How
can I do that?
3. How can I access to my other HDD partitions?
Best Regards,
