Selectable options for Reason for turning board off
 

I sometimes take it down to optimize the database or do backups. Is there a way to store pre-written messages and just select one when I shut down the site, kind of like the same thing the Canned Text hack does?

Try this:

Hmmmm, looks good. Is there another way to do it to add a more lengthier message? Also, I like to have the query on hand that undoes the original query before I install it. Do you know what that is?

You can add more lengthy message by editing the value. For the original query, ill do it now

EDIT:

[SQL]
UPDATE `setting` SET `optioncode` = 'textarea' WHERE `settingid` = '2' LIMIT 1 ;
[/SQL]

How would the user see the message if the SQL server is down?
