The GuaGua forum system is a lightweight and thin forum system with extremely fast access speed and simple use. The program code is concise and rigorous, the entire system program is only 400K in size, has powerful functions, and is completely free and open source. Can be used to build help forums, enterprise product knowledge bases, education, consultation, Q&A, etc. In today's increasingly complex and bloated forum systems, perhaps GuaGua will bring a breath of fresh air to users.
