I've had several people ask me questions on the profile instead of the private message site. Remember, if you post it on the profile, I am limited to 140 characters for a response. Many answers simply can't be made in that space. Instead, scroll up to the top line and beside my name is an "Inbox". Click on the envelope, "start a new conversation",enter the name of the person you're questioning, and then ask your question. From there, responses are unlimited.
