With the latest downtime of dot.tk, I've decided to move to actual domain hosting and grab a .org domain. This will remove the random downtimes due to the domain being unavailable which have been often enough to be annoying. Sorry to anyone who's auth gets moved for this.
Once dot.tk comes back up, the auths will still work for @lightron.tk for a couple months into 2014. I would suggest starting to use @lightron.org though as that will very likely be the new permanent home.
For people using the server hosting, the control panel and everything should be available for you with minimal issues. If something is wrong with the hosting or one of my servers, please let me know and I'll fix it as soon as I possibly can.
