Good points. Let me add this to make sure you know. If you post an application in LFG system on someone's game offer... If anyone replies in the thread you posted, you will get a Notification at the top-right of Roll20 (the pink drop-down). The GM also can reply with a special link called the Invitation to Join Game. Once you're invited to a game and you click the Join link, from then on you will start receiving Notifications for posts in that game's forum (not its LFG forum, but the actual campaign forum). Once you clicked to read or delete the Notification though, that Notification link might go away. So you want to be ready to read the post and respond, or at least keep the thread open for later or bookmark it, if you click the Notification link. Martin , unfortunately, if the GM does not respond to your post in the LFG, and the GM closes the LFG, you won't get any notice or reply. If that happens then it's time to move-on and apply for a different game. The reason is, the GM responds to the people they are accepting/inviting into the game. Yes I agree it would be nice if the GM would reply "sorry we are full" to the posts that didn't make the cut. Some do. The reality is, often GM is faced with 10-50 applications or more, for maybe 5 spots. The GM is focused on getting their game going (which takes work, preparation, attention). They may not have time to focus on answering everyone who they didn't choose to invite into the game. GM becomes busy dialoging with players who are in the game, about making the characters, setting up the rules, agreeing on play-times, and so on. I think my advice would be, stick to it! Keep trying and applying. Make your application/introduction post as good as it can be, to be appealing to the GM. It might help to encourage a reply if you specifically write in your post "Please reply to let me know either way" or even "If this is not accepted please tell me how to make my application better for next time" or ask them "What are you looking for in a Player?". Also just don't take it badly if they don't reply, since the GM is probably overwhelmed with applications. There is actually a very good community on this site, so I hope you find a game soon and start to enjoy the fellow users.
