I suggest a discord server and a patreon. That's what works for most fvns!
Also am very hyped for next updates
Usually vns offer 1 build or 1 month early access to updates and maybe some polls. A backer only discord channel for patreon build spoilers etc.
Oh the prices you can check popular fvns. There's usually a cheap entry tier, anywhere from 1 to 5$, and higher tiers sometimes even give nothing but thanks and maybe a discord role.
