Yes, I have a spot for that in my "draft" copy.
Limited to only the top line of fish, no more than 3 of each, and you need to learn how to type "testfish"?
Anything else?
Oddly, I can't find this in writing anywhere.
Perhaps I haven't searched in the right place(s)?
I fuzzily recall that there's some mention of some limit somewhere in this forum, but (like you) I couldn't figure out a good set of search parameters.
The only thing I can find is a discussion of why the limit isn't 3 fish (total).
I suspect that only Jim can provide a comprehensive list of the Testfish limitations (or perhaps Morgan, now that he does tech support).
