I'm afraid this is the first I've heard of a "writeback" flavoured Blosxom. Try dropping the "/+writeback" bit from the end of the URL.
I originally presented parts 1-4 of this five part comic strip in a previous version of my site.
In a sad and George Lucas-like effort of folly, this new presentation of part 1 has been digitally renovated, with corrections to artwork, new lettering and some changes to dialogue.
More will follow as I clean it up, though I can't pretend that I will ever manage to finish the incomplete final part...
