Gus, thanks for posting the icons directions. When we first set up this new site, PatriceJ and I found this 'trick'. I'm just so surprised that there are so many folks who do not have the icons as a default.
I'm glad that your surgery went well enough. PT is the answer. I've known several knee surgeries that went well the first time and not so well the second. When I had my shoulder surgery, I didn't get my full range of motion back for almost a year.
