In English... here's the explanation:
Monday we relaunched 
www.passionmsx.org and decided to redirect all visitors of 
www.msxgamesbox.com to Passion MSX. Technically speaking, Passion MSX is hosted in a subdirectory of my main msxgamesbox account and in order to get 
www.msxgamesbox.com point to that Passion MSX directory, I had to change a part in the servers kernel.
Hence, problems arised with 
www.msxgamesbox.com/karoshi as it was looking at 
www.msxgamesbox.com/passion/karoshi ... euh! Still follow me?
After a few hours work and digging what was wrong, I finally set everything back as it was... with one exception: 
The official URL of the karoshi forums is now 
http://karoshi.msxgamesbox.com and all links within this forum should use this structure. Hence the problem with the smilies... since it looks at 
www.msxgamesbox.com/karoshi !
I will quickly look in the admin panels if this something easy to change now.
Sorry for the inconvenience caused.
