I am starting a new community. I will have a lot resources and links so I need to choose the best forum software for that kind of forum. I will share movies, songs, games, tv shows, web resources etc. I need a good Download System and stable software. MyBB It has a nice default style. I like it. Tons of plugins. Good community and extra support. SEO is good. Admin panel is very good. MyBB is easy to customize. vBulletin 3.x Very good software. Very good SEO, very good default style. Everyone love vB3. I love it but it's old. XenForo Very light default style. Good SEO, fast and stable. Very good download system. What is the best forum software for big files and which forum software has the best SEO (MyBB, vBulletin, XenForo)? Thanks in advance.
