No problem, nice to have a chance to be of some use.

BTW: I do have intentions to use the SOM code for multi-document  
mapping. Goal would be to give a single page, automated overview of  
all major wiki content, and some navigation to quickly get there. Plan  
would be to treat each wiki page as a document and map it onto a space  
for all wiki pages, a visual content map with click-able links. I'm  
still pondering the features best to train the map on, the obvious one  
for me is the word association metrics I'm already using, but it could  
be useful to use in/out links as the features instead. Features would  
then be a large sparse matrix of links between pages**, should be  
quite doable for a single wiki.

** I imaging the map this would produce would be islands/mountains of  
interconnected pages due to topic links, more related to the actual  
wiki structure. Using word association metrics would give a structure  
based more on the actual page content.

P.S. David, did you see last weeks IAEP SOM? With it being such a  
quiet traffic week, your Wiki admin updates made you quite the focus  
of attention :-)
