It helps to post what time zone you are in, and what hours within that timezone, what days you'd be around to play. This site serves the globe. Most of the games are USA time zones, lesser UK, some others. Also there is a huge ratio of players to GMs so you might get more luck by applying to threads of games looking for players. there's enough that only the most thorough DMs go seeking players like yourself, new to roleplaying, and or roll20.
