The hosting here is WordPress for your easy to build solution, it would be possible to host here by using your wix files, but you will not have cpanel access to your files, and updating will be extremely difficult without the wix builder, etc. I would not recommend this in the WA environment, which is set up to sort WordPres. If you are a technically sophisticated user you might attempt this, but if you're looking for an easy to use solution, just go with the WordPress hosting.

Wix is different than WordPress. Wix is it's own website building platform.

There are methods and plugins for migrating Wix to WP, but for site design, you're talking about themes. You might be able to choose a WordPress theme and modify or customize it to look like (or at least close to) your Wix site, but I don't think you can just "port" it.

Here's a plugin.

I know your question has been answered, but I'll give you my opinion of the system. I am new to all this and am in constant need of technical help and practical direction. As soon as I write a question or ask for an opinion, a number of people give me very good, profession answers. I consider my WA ranking to indicate what I am putting back into the WA community despite the fact that I am a novice. I hope to encourage others, learn from others, help others, celebrate with others and uplift others.

It's tied to the Ambassadorship, which is explained here: Be an Ambassador at WA in 2016! ~Jude

Just shows a members level of engagement in the community - it has no real value - lots of members make the mistake of focusing on getting a high rank here -

Your rank here has no bearing on the success of your online business - focus on building your business and don't worry about your rank here.

It is a way of distinguishing how active a member is on the site.
