Isn't that like asking an alcoholic if he wants a drink? I can't say
no! :-)
I think the question we need to ask ourselves is, "Is this something I
can share that someone else will find a use for?" I am happy to add
anything you think is worth adding.
As for the size question, I did have Joachim Scholtysik send a zip of
the VisPro forms and code for his submission but deferred using it in
addition to the html of info he sent. (for space reasons) We discussed
it a bit and I think he has convinced me to try to set something up to
archive this type of information also.
I will be checking into this and will let you know if there are any new
developments.
