New member that doesn't even own a frog

Hi everyone I just joined because this place seems to have so many people with great knowledge about frogs. I do not own a frog, but have been taking care of my brother's PCF for a long time. He found it in an open oil drum while working at an auto repair place. He took care of it for a few months while at college in Northern California then when he returned home to Southern California we both split the care duties. I have many questions about it, most of them are answered with some googling, but most searches end up here, so I figured I'd join and see what it's all about.

I have already learned a lot about frogs from here, but there's always more to learn. Anyways, just wanted to introduce myself
