How to submit a patch to FreeBSD project?

[Unga]

Hi all

Recently I have submitted a patch to the FreeBSD current mailing list, it seems the patch is not applied yet. (http://lists.freebsd.org/pipermail/freebsd-current/2008-July/086814.html)

I'm not sure whether the FreeBSD project does not accept patches from non-committers or may be I did not submit it right.

How do I submit a patch to the FreeBSD project?

Kind regards
Unga
