They can simply create a new Custom BBCode to accomplish this, so no MOD installation is required to implement this functionality.
Tell the administrator to add a new Custom BBCode by going to the ACP => Posting
tab => BBCode
(on left) =>
and click Add a new BBCode
button, then have them enter the following information into the respective fields on the page:
Code: Select all
Center content: [center]Your Centered Text Here[/center]
And, if they want, they can check the "Display on posting page" option to make it visible to users upon posting.
Then hit Submit and the new BBCode will be added.
Just send them the link to this thread if they need the full explanation.
