I also filled out the form and didn't receive anything back. I wasn't sure what your turnaround time is on adding new writers. Not trying to bug you, but I was just wondering whether to interpret no response as:

1) Better Advice isn't interested in adding me as a writer.

2) Better Advice has a long line of interested writers and I'm some place in that line waiting for you to check me out and vote yes/no.

3) Better Advice is having technical difficulties and my form submission got run over on the information highway. I should probably resubmit it.

Any clues would be appreciated.
