I am planning to add a "reviews" section on my Q2A Site. Only admins will write reviews but members can vote and comment. It is basically based on blogging or article CMS.
I see that there are two blogging tool, one semi-premium by JackSiro, and one premium by Ami.
I tested the JackSiro but it's buggy, in fact, it failed the first try. But it seems that Arjun Suresh's Q2A site is still using this. But his forked version on Github got deleted.
Wordpress is the last choice because I have to create another database and most Wordpress themes are complex and have speed issues.
