There are actual groups out there, I notice many every day even though I am not looking for one. To facilitate your group finding though, how about you give us what kind of D&D 5e games you are looking for? What time frame and time zone, what kind of setting, what kind of roll vs role ratio, Homebrew or vanilla modules etc. The real problem is not that there are not enough D&D 5e games, but rather there are not enough D&D 5e games that fit your preferences. If you are having a hard time finding a group then keep posting in the LFG until someone answers, if you make your post attractive enough a kind GM might take you under their wing. Make sure to be as detailed as possible to your availability and what kind of player you are etc.. Most GMs will not bother with applications of a single line, especially with long term campaigns.
