Disabling user registration and pointing people to a contact page

[ShyK]

I know this may seem like an easy case but I'd like to verify what's the best way of doing this.
I manage a small forum that only has a few registrations from real, living human beings (as opposed to an insane amount of bots, no matter with what anti-bot measures), so manually registering them myself would not be a problem at all.

I suppose I should just "disable new registrations" completely in the vB options. If so, then is there a "streamlined" way of changing the "Sorry, registration has been disabled by the administrator." text on that page, or do I have to modify some php file in every update?

Thanks.

Edit: alright, I figured I had to enter a "translation" for that "phrase". If anyone has any suggestion (except attempting to deal with neverending spam), let me know.
