first time using roll 20

looking at getting back to DnD but open to try new system but new to the whole roll 20 scene so have no idea what to look for please help

Welcome to Roll20! As a system agnostic service all systems are catered for (popularity will likely match your expectations in most regards). To get started I'd recommend checking out a couple of threads: [Read First] Posting to LFG & Paid Games Helpful Hints, Tricks & Guidance Thread Repository There is also a slightly out of date tutorial that will give you some idea of how to use the VTT or you can create a game and have a play around to familiarise yourself with the site. This video from fellow Forum Champion keithcurtis is a great place to start as well!
