I will try and test the PHP in the next few days. I'll post here if it does, or doesn't work.
I agree with panigrc that long links are a pain too, but I think forcing HTML linebreaks to get them to wrap (which is what the PHP does) would break the URL?.
Of course, the same can be said of any code, so there is a trade-off between preserving your site layout and preserving the data. At the end of the day, the scrolling box may be the best solution.
A thread is for life. Not just for Christmas.
