So, for anyone who has a moment a day to spare and is willing to use it to help projects that are working on habitat preservation for various ‘big’ cats, check out Care2.com’s ‘Race for the Big Cats’.
Disclaimer #1: This is a donation site that functions on page views. They don’t have obnoxious popups (at least, in Firefox, which is what I use when visiting it; I haven’t tried to do an in‐depth analysis of every bit of their site with various browsers). But if you care about the spirit of the thing, you should spend a few seconds glancing at the banner ads on the resulting page, since that’s where the money donated comes from.
Disclaimer #2: If you don’t register, the donation will still happen, but it won’t be tracked as anything but an effectively ‘anonymous’ donation. So if you want a warm fuzzy later, register.
Disclaimer #3: The link above has a basic ID code embedded. The sum total of anything I get out of that fact consists of a warm fuzzy that you went and a clicked to donate (if you do so at all — if you don’t donate, I get no indication you ever visited), and, if you register, a link on my ‘friends’ page that provides a shortcut to your public profile (however much or little you put in it). If you object to that for some reason, however, a casual inspection of the URL should make it clear how to get to the site without the web bug.
Disclaimer #4: They appear to be legitimate, and they haven’t spammed me yet, but I can’t make any guarantee they will never turn psychotic and evil somehow. So use whatever precautions you should, when giving them an email to register. I believe the default account settings do have one low‐frequency mail turned on, as a general reminder/status update, but even that can be disabled as far as I can tell.
