A big welcome to you, too! You will find excellent support and ideas here, from folks who have been there. I have the same type of neck issues-sometimes cracking, popping or sticking. Can't underscore the previous posters' suggestions about stretching enough-it is what allows me to be able to back out of my driveway while turning and looking, something a lot of AS/Psoriatic Arthritis sufferers can't do.
One thing I learned from an orthopedist, sometimes with these conditions the natural curve in the neck straightens out-not a good thing! So sleeping with a cervical pillow, towel roll, etc. under your neck can help stretch the muscles and restore the curve. Good luck, and keep us posted on how you are.
