Welcome back to Lotuseyes!

Ooops! I did it again! I changed the site!

All your old Links are broken, sorry for that, honestly! But I had to do it. I found out that I'm not a wiki guy nor am I a blogger. Just can't use these sytems in an effective way for my purposes. I tried! I really tried. But I failed. Now I finally admited to that and installed a CMS. Here it is. Have fun!
