When choosing where to get your new forum hosted, free or paid, you always need to check their support forums and how the traffic is there, are the mods very active, are the admins active. You need to find out these things before you get the hosting, you should also go to teir support forums and ask fake questions to see how fast and what they respond. You need to do these kinds of things before you get your hosting because when you have a problem after getting the hosting and it cant be fixed, there is no turning back.
Support forums like Forumer and AON Central not much help, for example look at this thread in forumer entitled Custom Skins, and still no answer, and I cant even find one post in AON Central because the site was down when I tried searching. I know what your thinking, one thread does not mean that the support forums are bad, well no but its not just one thread, there are many like those at forumer, I dont want to publish them because then I would be known as a Forumer Basher which is not what im trying to do. Also in AON Central, just because its down for one time it does not mean its a bad support site, now the thing is ive been checking for a few days now and it has been like that for three days. Those are things you dont want we you are in need of support.
There are also good support forums like PHPBB City, Hosting-PLUS and SMF Host, they have a great support team of Mods and Admins that are there most of the time to help you with your problems.
But you can also find alternative support in sites like PHPBB Styles and the PHPBB Official Site.
