I like that it is easy for people who are new at this business, or don't know how much they should charge per post/comment etc., because there's an option of what price range their posts fall under (ie $0-$5).
It can also help with SEO if used correctly! There isn’t anything i dislike about Admingle so far but maybe more options would make things easier? If someone has no idea where to start when using ads then definitely give them some tips as well such as pricing ranges - just google "ad mingles basic guide"and follow those steps :).
