37. • Avoid shared hosting
• Get familiar with doing manual backups and restores.
• Get comfy managing your database, Multisite databases get
big and need looking after
• Be vigilant about the plugins you use and don’t forget to
check for multisite support before purchasing premium
plugins
• Version control is a really, really good idea (not just for
multisite, actually).
