The problem with using free web hosts is that you share resources, including the application pool, with all other users.
This means that not only do you have to run a version of web wiz forums
that doesn't have all the features and doesn't have the performance of
the main version, but also others using web wiz forums on the same
server can affect your installation.
Your best solution, if you want more than a handful of posts, is look
for a decent paid web host and use the full MS SQL Server version.
www.webwiz.net offer hosting with ms SQL Server for as little as $6.99 a month, just click the link at the top of this page.
