Yes, both discord and the forums here can help find people to play with. You might also look at what adventures exist, and see if people are playing those games that you are interested in. This can put you together with people already playing, which helps a lot.
Generally if the game has a role already, it has a text channel you can use. If not, then Adventure discussion is a good channel usually, although people are not guaranteed to have interest.
Just remember that people are busy, have their own interests, and sometimes nobody is currently interested in a title. For example, I have been casually jaunting about in LOTRO for years, and only in the last couple have we had much group interest there (and some of that vanishes as people see if they really like a game, which is normal).
