To answer your question: I used thumbs_up for voting, acts_as_commentable for comments, clearance for authentication and paperclip for file uploads.
I found thumbs_up before I knew of ruby-toolbox: I went to the acts_as_voteable github page, clicked on "Network" and scrolled to the right as far as possible. Most rubyists are very active on github, and a lot of the packages are forked.
Thank you :) I was looking for something that integrates rating (not voting) and commenting in one package. I found this https://github.com/grimen/is_reviewable through the toolbox. But last commit is from 2009. Hopefully someone has forked it or I will have to fix it
