Good job. I'd make them available at my site too, but as far as I know, I don't have the capability to store files. I've been working on and off--and on again now--with trying to develop a rudimentary online dictionary based on the NAKL vocab list...just debating whether to restrict myself to the 3,000 A- and B-class words (which even at 3,000 entries leave out a lot of commonly used words) or do all 5,900 entries, which means it'll take forever to finish the task.
Oh, is that the frequency list you've uploaded? I'd recommend also uploading the "Basic Vocabulary List for Studying Korean," (한국어 학습용 기초 어휘 목록) which the NAKL published around the same time. Much more useful than the frequency list.
There are links to the NAKL pages for the Excel, text, and Arae-A Hangul versions of the file at the top post on my blog (http://21cseonbi.blogspot.com/2006/08/korean-vocabulary-list.html)—see 2nd para of intro and footnote 1. I also mentioned the list on the "Let's Learn Korean" page you link to above.
It's up to you whether to upload those files or not, but to my mind, they're much more useful to Korean learners than the straight-out frequency list. Anyhow, both are useful resources.
