Help me out please

Hey I have played DnD before a few years ago I used to play every weekend- But on a table. I don't really grasp how this works or anything could someone just maybe give me a run down in a paragraph or something?

Roll 20 is a virtual table top. Without magic (API), it is basically just a blank canvas for you to have little tokens on that you can move around or have your players move around. To be more complex, it allows you to store multiple 'tables' with pretty pictures that can make it look like a legitimate place for your players to pretend like they are at really. This allows you, as the GM, to move players around these 'maps' to further your game. The tokens can store minimal information too. They can have three visible trackers that can be assigned numbers to represent many things, either hp, mp, wounds, stun, ammo, plot points, fate points, health potions, etc etc. These tokens can also store 'attributes' which are more numbers so you can save some information about each character. There is also a chat function that allows everyone to type into it. This chat function also houses a pretty good dice engine for players to roll with and allow the GM to see. Basically, its just a tool, not a game.

Thanks man, so like I would get into a game with a GM in that LFG thing , Have a premade char sheet ready, and just have it in the background on a notepad or something and send him one? And when the game is to start, do you join a lobby or like, how does that work? Lol sorry to bother wanna play so bad though.

Just like you would find at various face to face games, each GM is going to have his or her own way of doing things. The best option is to dig through the Looking For Group Listings or the Looking For Group Forums and find some games you like the looks off. Then you can ask the GM what you need to do. I would also advice taking a look at the Roll20 Wik i to get a better idea how the application works. There are some basic Getting Started videos for both GMs and Players that should be very helpful. Each campaign has an individual link that the GM will send to you either through an invite email or a private message. Once you're part of a campaign, it will show up under your campaigns in your profile so you can jump in whenever you like. You can even create a campaign of your very own just to get a feel for things before you join a game, if you like.

Yeah, like Sarah said, GM's have very peculiar ways of going about things. Some don't mind you imported a premade character you have at the ready, while others wait until the group is gathered and then proceed to find out what players want and need to make a group. Best suggestion, post something in the LFG forum explaining that you are new to roll20, but not to tabletop rpgs. Tell people what time zone you are from, when you are free, and what games you have experience with.

as an example, some games i run you have a sheet printed out at your home. i dont use the whiteboard and the game is voice chat plus dice roller. other games i use the in game character sheets and map. some games i load up a satellite photo as a map. it all depends. good luck.

THanks everyone , all the tips have helped :)
