I have downloaded and installed "SMF 1.1 RC2 - install" on my hosting.Do I have to install "SMF 1.1 RC2 - update" file on my forum?It doesn't make sense to me when I read the description there"Use this if you have SMF 1.0.5 or SMF 1.1 RC1, or higher installed".Higher or lower.I confuse this.
If you are making a new forum, all you need is the install archive.
You can find out how to Install SMF (http://docs.simplemachines.org/index.php?board=2.0;sort=subject) in the docs.
