Melissa has 3 syllables. Fewer is better. Siri has 2 syllables and 4 letters -- and it's easier to say (phonology).

MelissaHome sounds like a command to a dog or a deprecating command to a child: "Melissa, go home." Wait, forget about the "go." "Melissa, home!"

Never start with publicity. Start with what is right for your audience, right for your brand, right for what you want to evoke. MelissaHome does none of these things. Go back to my previous post. If you do stick with "Melissa," for the sake of argument, put a verb in front of it. When I did a project for a high-end antioxidant drink company, they had a catchy brand name but a difficult to spell ingredient (can't say here for confidentiality reasons). The website I suggested and that they use today was Drink<BrandName>.com -- because that's what they wanted people to do: Drink It! The ingredient was a feature, but not a benefit in and of itself and moreover, it was insuperably difficult to spell or pronounce.

You should think along the same lines.
