I am a novice at this kind of stuff, and a novice at PHP at that. Why PHP? Simple. My $5/month server does not support any other CGI, and PHP is commonly used anyways.
Anyways, I have attempted to create my own anonymous bulletin board script, which is similar to kareha here, which is so far purely procedural, for I have no experience with OOP, and I will not even try working with that stuff. I am doing this because I want something that is more straightforward than kusaba to work with. I have taken a look at kusaba myself and I have decided that I do not want to deal with modifying it to make it any "better," as it looks very cumbersome to deal with.
It is not an imageboard. I am not a fan of imageboards. I used to be a fan of imageboards, when I first thought that imageboards were some kind of gathering place for culture. Well, experience on the imageboards has told me that those people are probably not just pretending to be stupid. I have especially disliked those /h/-"hentai"-type boards ever since I have known that those kinds of imageboards are typically full of people who just leech, who are typically haughty and care not for anyone else nor for any community or anything meaningful.
The PHP for this software may well be a jumbled mess, since I tried to do it as quickly as possible, and have paid little attention to how it will perform. I myself am not an expert in computer science and algorithmatics, and I know little about how to make it efficient anyways. I am not an expert programmer. I might eventually study or self-study computer science and programming paradigms, but this is what I have come up with so far. Regardless, it has at least been workable for me at least, which is why I seek to use it for further developments eventually into a fully-developed BBS software.
If you wonder what the name "Lucid Tea" means, it doesn't mean anything. I am just playing with words here.
It is half-completed, and the things that are missing right now are setting a style for the site, and the moderation. Installation for the software is done through the install.php file. Configuration is done through editing the settings.php file. I based this installation off of Simple Machines Forum and how they install.
Take this half-baked software for what it is: done by a novice, half-baked, half-finished, and done hastily, but at least something I can work with, and which I will seek to complete soon.
Here it is:

But yes, I am not using it right now, because yes, I am a little hesitant about using it in the first place.
