No problem, you can easily get the post by welcoming new members in the WF New Member Check In - Jeep Wrangler Forum
area. The rules for posting in the wanted and for sale sections are here: Classifieds Rules
You don't have to be overly active (we have lots of those people). I can relate, I am an older guy and this is one of my only shots at social media. If you have a question, most folks are pretty understanding since they, at one time, were probably in the position you are, nobody is born driving a Jeep despite what some folks say.
Look around the forum areas and you can see there are people with the same and even less experiance as you. Probably every question you could ask, has already been asked here before so you are in good company.
