This sounds like an excellent way to clunk up something fun with a whole bunch of politics and rules.
What do you mean exactly?
If I understand you correctly, then I think your reply is uncalled for. I'm merely looking for a way to keep things organised for people that are responsible for maintaining bigger collections of pins with more than one person working on these machines.
The problem that this club has is as follows: they have 70 pins and you know what will happen with these machines: malfunctions are being reported, maintenance is needed, some need restorations, in other words: there's always work to do. Fortunately they have volunteers. The problem is getting the right info with the right people. Sometimes a malfuntion gets forgotten, sometimes people start working on a problem that was already solved a week earlier by somebody else, sometimes parts are ordered twice, etc. So they need a system to keep record of all active problems, work progress (one might run into problems fixing something and gets the job half done), parts needed (your work halts when you need a part that you don't have in stock). When this is a private collection and you do all the work alone, it's no problem: you know where you were last time you stopped. But in this club lots of volunteers work on a machine and sometimes somebody else finishes a job that you started.
Sure, you can also take a folder and stuff some papers with notes on it in there, one file or sheet of paper for each machine, but I was thinking of a more elegant solution and was just checking to see if there is any need for such a system. I have 6 pins myself, so I can remember my own things to do
