MAXUSERS isn't the maximum number of users.  It's just a configuaration
parameter that is then used to set other limits (for example, the
maximum number of file descriptors and processes available to the
entire system).  Look at a ports "arch/foo/conf/file.foo" file for the
"maxusers" line to see what the available range is.

On my home box I have:
	
	options         MAXUPRC=500             # Something reasonable.

in my kernel config file, and

	ulimit -p `ulimit -H -p`

near the top of my /etc/rc.conf (Yes, there's probably a better way of doing
that).
