Wow, thanks for all the great replies!
Cuppamerlot, I appreciate the advice to be bold. I find it difficult to talk about myself, but that is an instinct I am obviously going to have to master. Out of curiosity, what aspects of your profile made you a particularly strong applicant? I have been surprised by the results that some of the regulars on this forum have received so far, all of which seem to demonstrate that even ostensibly strong applicants cannot be certain of their outcomes. What strengths did you have that convinced you to "take the plunge"?
Fuzzylogician, you've mentioned in the past that research experience is vital, and I will have at least one summer research internship before submitting my applications. I will graduating in December, one semester early, for financial reasons. Do you have any tips about how to gain research experience post-graduation? [Also, my syntax professor spent last class ardently defending the Internal Subject Hypothesis--So I know what it like to be courted for conversion!]
