Hey there, welcome to SotE!! I'm sure you'll like it here, everyone is super friendly and helpful (this was my first experience with forum RP and I had a LOT of help getting started haha).
As for advice, I'd say make a character you love and then check out "open plots", or just pimp out your character in the plotting section ^.^
(Of course I personally am always up for more plots, and I know a couple other people who are as well, so you can always just hit me/someone up with a PM!)
