Hi James, Welcome to RSCR.
RSC is a much slower game than RS3. That itself might take a bit of getting used to.
It has a bunch of other little quirks like not being able to eat in combat or run for the first 3 rounds.
And you'll quickly notice that it's missing a lot of the QoL features that you're used to.
Some extra things have been added to this server though. Like batched skilling, which you'll start to see from levels 20 onwards. Originally we had to click on every individual shrimp to cook. It was very tedious.
These forums have a wealth of information.
I'd start with these threads.

Helpful links & commands!!!
And for when you start doing clues.

There's a map in game if you get lost, but it doesn't work too well if you're using the Android client.
Here is a link to this server's full world map.

Feel free to add me ingame and shoot me a message if you have any questions.
Or you can ask in global by starting your message with the ::1 command. eg. ::1 Hello World!
Take a quick look in the Client Settings, found under the wrench icon, when you get on too. There's some things in there that aren't default settings that you might want to change.
