Welcome! Sounds like you’re off to a great start! I also am new, and currently on my second sit. This season (Thanksgiving/Christmas) is a great time to get started as a sitter, with so many HOs going on vacation.
I noticed you tried to link to your TH profile in your forum profile, which is a great idea. However, the link is not quite right; it goes to the user’s TH profile (e.g., if I click, it goes to my profile).
