Hi Evan. Welcome to BC. Your willingness to help is much appreciated!
It's really great to have someone so knowledgable join the community.
I like your attitude, too, re not knowing everything. Shows how smart you are. We're all here to learn and share what we know. Just keep in mind we cater to newbies. So try to keep any advice as simple as possible.
That's not to say that you shouldn't post about advanced subjects. Just do what feels comfortable.
