Can someone please tell me best way for developing forum, so that I can integrate it in my rails project. Note:- For rails- 4.2.3 I have already tried forem and thredded, but they seem outdated or not well maintained(developed).
Yes people these days are developing forum using other tools. If you still want to built forum in rails you can refer http://www.sitepoint.com/forem-rails-forum-engine/
