"I may be interpolating from what I know of motorcycle helmets, the construction of which is essentially the same (the risk of failure being a little greater), but the prevailing wisdom in that world is to use a helmet 5 years then junk it."
Wow. Didn't know that.
I guess that's part of why I get so concerned when information isn't put right out there. I can be really oblivious to important things, even when I'm trying to pay attention / seek out what I need to know. So when I hear caveat emptor stuff, I think, great, but some of us seem to be inherently better at that than others, and so those others are just basically screwed.
So I don't know. I realize FreeCycle isn't in the habit of making rules to protect members from themselves, but I guess I'd like to see a list of cautions and advisories, maybe on the post that goes out once a month or so. It could include advice about helmets, a link to a recall list website, other specific items people might not know to be cautious about. I know what I should do at this point, which is write to the mods again and make this suggestion/request. I just get really nervous bothering them, so it'll take me a while to psyche myself up to do it.
@dwillen: re directly emailing people who post those offers, I have a feeling that's frowned upon, but I've been sifting through the rules and haven't found anything to that effect. Maybe I dreamt it. Thanks for the ideas. Thanks to everyone for your thoughts on this.
