The challenge is that
A) The Amiga doesn't have many office suites
2) Those that exist are rather old
iii) They're not freely distributable.
Check Amiga Future's software database (ASD) for details as to what exists, then try to find it. If something's not on Aminet, it's probably because the author wants to control distribution.
Hypothetically, if Wordworth were available for free download only from Digita (it's not), you could conceivably upload a text file to Aminet explaining just that, along with a URL to their download area. If you search, you'll see that such a thing was fairly common in the days of restrictions on GIF software.
