texte = Hmmm, my very first thought is to [listwords] with the space char. as a d= elimiter, but it might=20 end up being process-intensive if you have a lot of it going on. If you g= ot this route, it might=20 be best to detect and change to live URLs then write them to the .db rath= er than detect and change=20 on-the-fly upon every display.

[/url][word][url][/url]][word][/grep] [/showif] [/listwords] I grepped [url]'ed spaces in the [listwords] since multiple chars can't b= e delimiters that I know=20 of and you'd need to force user to enter "http://" or detect and add your= self if not there.

This really seems overly-complicated to me, but it was my first thought, = and an incomplete on at=20 that.
