Thank you for all the advice, everyone! Thankfully Yssing has stepped up to the challenge to make the forum for us, and currently we have some hosting provided which we'll be testing out to see if the PHP-Fusion package works on it.
Although the idea of a BBS is kinda cool in an oldschool way, I think a regular web forum might be more familiar for most people to use.
Johnklos, if the server we're using doesn't turn out to be sufficient, I'd love to take up your offer for hosting. Out of curiousity, could you tell us more about your server?
We're just working out the particular sections and settings the forum will need at the moment. If anyone has any suggestions for areas which an Amiga games development forum might require, let us know. We'll probably continue to fine-tune the forum once it's up, but it would be nice to have it laid out well for everyone to jump in and use straight away.
Ideally we will have both public and private sections of the forum, because there are still a few developers who like to keep their projects under wraps at least until they're happy with the direction it's going, and others might just have some ideas they'd like to keep a secret for a while first. So the private section would be for developers only, and the other sections will be accessible to all forum users and readable by guests.
As well as adding a section where people can ask for help with games, and maybe a section for our open-source game maker engine once it gets started, this is what I've come up with for the forum so far. Please feel free to suggest better names or organisation than this, I'd prefer keep the forum more grouped together, less redundant, and we don't need any off-topic area.
