Autism BBS

Lately the technical imperfections and design of shiichan started to get on my nerves(not including the constant shitposting) so i decided to create my own BBS. The feature set is not finalized yet, and some improvement in design might be possible(comment?).
Here is the first draft of what is coming:
* Open Source, using only free code
* Performance/bandwidth oriented
* Minimal processing, no BBCODE,only filters html tags and autolinks URLs
* C without any OOP or platform dependent code
* Very spartan text-only design, no CSS/JS or any external files
* Threads are stored as files in directory as ThreadName.Page generated as follows: 16 char random string THREADID and each 1000 posts(numbered from 0 to 999,1000-1999,etc) is a new file. e.g. /ls78saflGKsu9238.0  is first(zeroth)page of thread ls78saflGKsu9238
* replies consist of post number+text only, no name,email or timestamp, First line of first post in the thread is the thread title.
* Replying to a thread reloads the same thread page,like noko.
* no sage or bump feature, instead there is such system:
1.each new post in the thread swaps its(thread list) position with thread one cell higher(if at top, no change). If the post contains the same text as any of previous replies or only a quoted part of previous post, it does not change the order.
2.new threads start at the top of thread list.

Update:
* User-based moderation, each new thread will be given a password field, so that thread starter can moderate posts in his thread by clicking (Hide) and viewers can bypass that by clicking (Post hidden by OP|Show hidden post){which will be part of page, with style=display:none}
* Reply form is a floating div which is transparent and follows the lower part of screen
* Reply form will contain a ribbon of JS-buttons editor(for people wanting WYSWIG, rest will just type [b]sometext with tags being one-letter for ease of use) like this
* Structure:
Frontpage|Thread Lists|Intrathread pages [0][1][3]
