This forum is closed for good. Expect new things to come.
In the mean time, I recommend you check the following places: VPW2 Freem, AKI Outsiders or MPire Mall Discord servers. If you really don't like Discord, there is the r/N64WrestlingGames subreddit, but there's no active development of mods/hacks there. Sean O'Connor's Youtube Channel is also recommended.
