I used to use pLog as my blog system, but after I move my hosting providor to DreamHost, I found that, WordPress is so Cool, and I decided to transfer my blog system to word press.
Except those comments was losted, all the other blog entry are all alive. :-)
That's most important!
WordPress provided a convenient way to transfer all the old blog entries via RSS 2.0, I had been confused by pLog's system by incorrect RSS Date format. For 2 days long, I finally found out that I missed the local files which I choosed in pLog system.
Of corz, when u know where is wrong, fix it will not be a big problem.
