Actually, for a short while, Dokuga and A Single Spark operated at the same time. Shortly before that, A Single Spark was having a LOT of trouble keeping the site up and running - server problems were numerous. Dokuga was the inspiration of our creator, Miss Kagura, and Demonlordlover (a legend in Sess/Kag fanfiction). It was designed to be a Sess/Kag site that would be more user-friendly, more closely monitored, and more interactive than 'Spark. Miss K did the heavy lifting of building the site, and Demonlordlover loaned it the name from the Yahoo Awards group, as well as creating the first set of our infamous RULES!
Shortly after Dokuga began operations, ~Winter~ (the owner of A Single Spark) decided that she did not, indeed, have the time to devote to the site. Miss Kagura made an offer to host 'Spark's archive in an effort to preserve all those wonderful stories, and ~Winter~ graciously agreed. Miss Kagura worked for months on the coding to roll the 'Spark archive into Dokuga - the result is what you see today.
I, for one, am incredibly grateful to Miss Kagura for all the hard work, sleepless nights, care, and effort she put into building this site and incorporating the 'Spark archive. Yes, we've had our glitches, but overall, the site has performed far beyond anyone's expectations over the years.
So, yeah... kudos to Miss K, and MANY THANKS to our volunteer tech guru, Mitharus - the guy that jumps in and patches up stuff that has broken over time!!
