The Internet has a handful of websites that offer the ability to make a forum, some for free, others not. Not surprisingly, Forums-Free.com are one of the sites that offer forum creation for no cost. Of course when using these services your freedom in what you can achieve is limited to that of a paid solution, but for something more casual and informal the options available are more than adequate.
The free forums available at Forums-Free.com offer up to 1GB of storage, over 40 different themes to choose from, and the option to personlise it to! To create a forum (phpbb) all you have to do is simply fill in a simple form on the site, you choose a name, the launguage you want your forum to be, and that’s it! For a free option, this may be worth trying, especially if you want to get some experience with phpbb before trying a dedicated solution.
