Yes it's good I like it but I notice theres a lot more spammers on it I help run a webmaster forum and I just checked it about 5 or 10 mins and there were countless spam posts I turned it offline to talk to the owner and see what to do and I also enforced a human verfication now for new users It's that insane
You will find loads of community programs all around the internet. The best one that is utilized by all of the websites is vbulletin. It's not really a free forum software however. If you want free then you may decide to try phpbb or smf.
vBulletin (vB) is one of the most popular premium forum software on the web, and the choice of many big websites. Some of it's built-in features include photo albums, groups, calendar, events management, polls, blog and more.
phpBB is the excellent free and open source forum bulletin board software. Its contains hundreds of style and image packages to customize your board.
XenForo is a popular paid forum software package written in the PHP programming language and developed by former vBulletin lead developers. It has built-in SEO features, powerful add-ons, recent activity stream, social engagement functionalities, etc.
I would have to say phpBB if you're going for free software, just because they have a good modifications database and it's really simple to design your own themes for it. If you're going for a paid one I would have to say XenForo. It is according to me much more modern and has many core features that other software lack.
Well, it is not a forum script per se, but I use Ning. The community has been running smoothly for about 5 years (almost 6K members now). I use manual approval and ask some questions to separate people from bots. Can't say that never have spam, it happens from time to time when they use manual registration, but for the most part, it is a safe environment.
vBulletin and Xenforo is consider as one of the best forum script. I see most of the webmasters using these scripts to create forums. These forum scripts are coming with great features and plugins to expand your forum with variety of options.
