What is the ruling on using the name "Subhan Allah wa bihamdih" (Glory be to Allah and with His praise) as a nickname in online forums or in e-mails, and is the one who does so sinful?

There is no harm in the questioner adopting the phrase "Subhanallah wa bihamdihi" (Glory be to Allah and with His praise) as a slogan for her in forums or as an email title, following the example of the Companions who adopted "Ha-Mim! They shall not be helped" as a slogan in some battles, provided that this slogan is not used in any place that leads to its disrespect.
