While the idea of a centralized DIY page is good, personally I have a couple problems with it. First, updating pages with pics or information tends to happen next to never. Second, I get to watch where my traffic comes from and figure out what people are really going to my site to see. Third, I have to deal with twiddle dee the wonder admin on SuperHonda and can't link directly to anything HAN. And fourth, just because I'm shallow, I like the recognition I get hosting the how-tos I write. Not too mention when people have questions they're almost garanteed an overnight response if they email me.
BTW, engineering a way to retrofit a motor into USDM side mirrors to make them fold would be a headache twice the size of the JDM price.
