Working very well here, and it's a cool idea. I had no clue you could do something like that. What I'd really like though is a good search function, one that searches the topics' headings and contents, and sorts the hits according to relevance (with those hits that have the word in the heading having a higher relevance).
That would be cool...

I'll give a post as soon as I got some advancement on this.
