The disclaimer that's printed in red on top of the page explicitly disallows using the template for other purposes than submission to an INFORMS journal:
INFORMS journal templates are for the exclusive purpose of submitting to an INFORMS journal and should not be used to distribute the papers in print or online or to submit the papers to another publication.
So leave it as it stands and don't tamper with it.
If you're annoyed by the flashing red warning (and I understand you are), just add
\renewcommand{\theARTICLETOP}{}
before \begin{document}
, but remember to remove it before submitting the paper. And, please, comply with the notice and do not distribute preprints made with the template.
\theARTICLETOP
(seeinforms3.cls
file for the definition)..cls
file. You can make the changes in your.tex
file. Copy the original definition of the command in the premble of your.tex
file and make there the required changes. Notice, however, that the journal specifically required this option and that the template is to be used only for submissions to these journals with thos requirements. It's better not to change it.\renewcommand{\theARTICLETOP}{}
