One problem with an official or semi-official checklist is there are SO MANY different variations of participating in Lemons. Just look at all the advice/help/guidance offered to people in the newcomer's threads.
Having a looooong checklist of things to consider is tantamount to having a 3" thick rulebook for a newbie. It can help some and it can hurt others.
Some people are paralyzed when they don't have enough information. Some people are paralyzed when they have too much information.
When I tell someone they can build a tech-legal Lemons car for under $500, safety equipment included if they buy smart, someone else will come on and say a race-ready Lemons car can't be built for under $5,000. If I say 1.75"x.095 ERW and a tube-frames FIA approved race seat, and 12 year old radials off craigslist is fine for their 1984 Plymouth Colt, someone else will say they would never sit in anything that didn't have a Butler full-containment seat, 1.75x.120 DOM cage, and fresh date coded 190 treadwear Yokohama DaShiznit tires.
There are people who would NEVER EVER enter a hot track in one of my cars even if they were paid. Likewise, I have absolutely zero interest in sitting in a real racecar, and if someone offered me chance to turn laps in a Daytona Prototype car during an ALS event, I'd say "Thanks but I respectfully decline your offer" unless I could put a larger than life styrofoam replica of Judge Phi's head on the roof. Now, if they'd let me take the Moke out there for a few laps during an ALS event, I'd be all over that.
Point is, while we all have great intentions by offering advice. I think little tweeks of the existing resources (facebook twitter and instagram posts to the forum even to dredge up old, helpful info. Perhaps a hyperlink to a particular "Hot Forum Topic" at the end of a race spam announcement. When we sign up as teams, we have the option the check or uncheck a box to make our team info made public. I have NO IDEA where that goes. But those who select that option can maybe be fed into some clickable map based on city / location for a "Would you like to be added to our Resources in your Area map to allow other teams to contact you for help?
Just today's 2 cents.
Everything Spank just said.
I've had a number of people email me via the forums, either based on where I'm located (Team DadBod, for example) or what car I drive (new teams from both coasts building old Mopars). But that requires reading enough of the forums that you happen to spot the right person and send them a message; not everyone is a forum junkie like me. Making that kind of connection easier would be pretty valuable.
And at the track: why not add a step to the end of Tech/BS inspection where you mark your team's location on a paddock map (that the judges print out and leave posted in the penalty box all weekend), and make a note of any equipment or expertise you might have available? The easiest way I've found to get what you need in a pinch is to send a teammate walking in every direction (or just ask Anton Lovett, if available). Streamlining that process would also be valuable, especially for the more introverted folk among us who might find it difficult to ask a dozen different strangers for help.
