Not sure why, but for some reason, "COM_EASYSOCIAL_BLOG_COMMENT_SYSTEM_TITLE" is being displayed on the EasySocial Wall..
So maybe I leave it the way I showed you?Yes that is fine.
Should it be the default?It depends. If you want your users to use the blog on EasySocial, then you can make it default. If not, users have to install it themselves from the app browser before being able to use it(https://take.ms/If9AV).
Are the settings I have selected what is required or needed?Are you referring to the blog settings? I'm not really sure how you are planning to use the blog app. The settings should be pretty self explanatory.
