I learn everything by myself..
but i did some googling and didnt really understand much.
i reviewed your code from the that you posted from the other article and noticed the \doom\ code that you mentioned. I have no clue what that is..but if you could elaborate maybe I can understand more.
if you want I can email you my ftp/joomla login information so that you may modify and play around with the code freely. All I ask is that you have duplicate files on your local computer so that (if anything) ever happens, you still have backups of the old un-modified code.
