Compile transcripts of every TED Talk

I want to assemble one master text file of the transcripts of every TED talk on their website. the transcripts are readily available, but I'm not sure how to write a script to compile it all easily. But I'm sure one of you guys do :) [login to view URL] approximately 1500+ texts. I would like each of the transcripts as separate text files with the speaker and title in the file name and then one .txt file with all transcripts compiled.
