Sorry, you mis-understood - I was thanking you for suggeting the idea and letting people know that ideas are welcome - I alwys do my best to impliment peoples suggestions where possible but this one is very difficult.
As for this one, as nice as it would be I have no plans to impliment it because it will involve too much work and too many modifications to the source - the juice is not worth the squeeze so to speak.
If you can PM me the links to the forums you know are using source colouration that recognises which programming language is being used I will take a look (just to make sure that I am not missing something obvious!)
