Forumotion (www.forumotion.com) is very easy to use, and it does not take long to get your website up and running. Their admin control panel is great and very easy to use. Their uptime and reliability is unmatched from any other hosting provider I have seen, and when they claim 99.99% uptime, they mean it. Never once in my 3 1/2 years of working with forumotion sites have I seen a website go down.
The portal feature is also very convenient. This is something that is not always easy to set up with other forum solutions. (such as a clean install of phpBB or myBB). Another interesting feature is the ability to convert between phpBB3, phpBB2, punBB, or a very old version of IP board. The conversion has never taken more than 15 seconds and seamlessly retains all posts and users. It is worth noting that forumotion significantly modded these forum softwares, and they do not give the exact same functionality as a clean install would give, but the consistency in their services makes up for it.
Moreover, they have supports available in many languages, which is very useful in case of technical issues.
