[✅] Membership approval workflow

Does anyone have recommendations for the best approval workflows for new members? The site I'm working on has a free membership plan, but they need to be manually reviewed/approved before getting access. 

I found this article but I was wondering if these are still the only two workflow options for having a membership approval process? Or what others have done?

[✅] Personalized numerical data attributes

I am new to Memberstack and in the process of configuring it for a Duda site. I was hoping to be able to display personalized member field data like first name etc in the body of the site content, but was surprised to learn you can't display numerical data in this way. At least according to this article. 

Does anyone have any workarounds for this? For example if I wanted to show their age as a numerical data field on the site, or a points balance for example?
