From Jonathan Feinberg's Wordle.net site.

I understand Tagul has additional functionality, i.e. ability to have cloud direct a user to a specific URL or to a link within a web page, but I am afraid it requires more advanced knowledge then my skills.

I may just stick with Wordle because it makes pretty designs and requires little knowledge from me.

But I will continue to try to make test Tagul clouds and read the Forums for ways to accomplish various tasks.
