phpBB is the market leader for all forums
Fast and relatively simple to use
When Concrete5 have fully tested a site based forum which works I will switch and archive this forum. But hey ! it may never happen, so enjoy this forum at phpBB.
If you are new to forums, then a good idea is to read this article at https://www.wikihow.com/Use-an-Internet-Forum
Please do not use this forum for complaints, use the " complaint post " page.
