Welcome. You'll love this forum. I just started smoking last fall and had limited success until I found this forum. I have learned so much from the kind members. They are generous with answers to your questions and there are a ton of great ideas in the postings. One of the ways I learned the most was posting my projects with pictures and I always got support, advice and suggestions for differing ways to do things.
I am sure you will love this forum as much as I do.
As for a first time recipe, Ribs done the 3-2-1 method or a pulled pork butt would be a good choice. Just put 3-2-1 ribs or pulled pork in the search bar and there will be lots of recipes and discussions on methods.
