The SYC built a centralized branch structure funded by member dues

Evidence

The SYC’s message steadily spread among the population, and the organization established branches in many regions of the land to mobilize the public and orient its sentiments. Each branch had its own officers, but the final authority of the club rested with the central committee (CC) in Mogadishu. SYC members paid monthly membership fees, and its officers engaged in fund-raising activity during their weekly meetings. — Abdi Ismail Samatar, Africa’s First Democrats, 228
