WHOITTER micro-nano-pico forum CMS
Single-file CMS for creating a micro-nano-pico forum in which only admin can act as top-starter. to work you need php 4 and higher, does not require relational databases, everything is in one small file. All the rest have the right to comment without the need for registration, without the possibility of inserting HTML codes, and then something graphic. The only exceptions are Emoji, you can copy them from any existing source, or by entering from the phone (many have this software on their phones, so I see no reason to insert them into the program).
The administrator can edit topics with the ability to insert images, various formats, etc. pieces https://htmled.it/ - there are such visual editors with the help of which you can create and then format it as it should, and insert the ready code into the topic, after saving you can admire the result.
But there is also no connection button with the admin, what"s the point if the engine is created for maximum anonymity, however ... whoever wants to can leave their real data at their own risk, as they say.
Administrator comments differ from the others in a different color, otherwise they have the same functions, and the same restrictions, since they are comments and if you need to drop an image or video, you can simply drop the link.
