When i'm working on my site I dont like people to like refresh there page and somthing new to pop up so how do I lock my forum while im working on it?

Ex."This bulletin board is currently closed. The Administrator has specified the reason as to why below.
Fixing. Be back online soon!"
Ex. Gamer-Freakz.com

Visit the acp and choose the Board offline/online plugin group. Specify the reasoning and click yes. Done.

Or rename index.php in your root and add your own index.php with something saying "Back Soon" or something.
