I wish to add a very simple forum to a website which works without the need for logging in. It doesn't even need separate categories - just a continuous stream of messages. Its for the use of small group of people (50?) that may post an average of 2-3 messages per day in total.
I know it will be open to spam, but I would like to give a select few users the privilege to delete messages so that spam can be kept under control.
The number one priority for the forum is that it have a simple and friendly feel. I want new visitors to have the feeling that they are instantly "part of the conversation" rather than having to dig around to find the latest post.
