I'm Nataly, Magento Backend Developer, and I've been working with Magento platform for last 3 years. I hope I'll be able to share my knowledge/experience with you here. Currently I'm deeply involved into Magento2 at the moment, I saw many interesting questions and answers here, I'll try to contribute in next couple of days.
Hope you're doing well. I hope we can learn from you and resolve our issues with your informative knowledge.
It states there that abbreviations cannot be used either. However I know of brands that contains mage in their brand name, like for example mageplaza. Is that allowed? F.e mycompanymage?
