You can always retract the thanks that you give to people. Just go to a post in which you've thanked someone, and there will be a button for that.
Thanks, Ryan. I've seen that, but I haven't seen the points disappear with that. So, I believe that someone is just retracting. It's cool. People have the freedom to give and to take back. Again, I'm not complaining. I just haven't experienced it before (at least, not at this magnitude this quickly), so it was interesting enough to me to post it.
Again, probably should have gone in the boring thread...my apologies...
