1. I don't chat with people outside of Gaia that I don't know personally. It's a personal safety thing. If you want to IM with me, I'm usually signed in to my meebo.
2. I don't usually donate to people I don't have friended on here. I usually save donations for special occasions and when I'm not actively saving up for something and have some gold lying around. I don't really like being solicited for donations, but if you have a status up saying you're saving up for something I may chip in.
