DEVELOPMENT HOLD NOTICE:
ProcessForm is currently unavailable for purchase. The most recent release version (3.0.14) has been posted on the Scripts Page for anyone needing to download the scripts or documentation, and will be available as a free download until further notice.
We have not abandoned development for ProcessForm or NateMail, but due to our current workload and a lack of sales profits, we are unable to keep up with support and development, at least at the level of quality that I've come to expect. I expect to be able to devote more time to the project in the near future, but until then, please use the download link referenced above.
If/when the next full release version (4.0) becomes available, it will most likely be a complete re-write to update the source code. Current plans are to offer discounted upgrade pricing to registered users of the existing ProcessForm script. Thanks for your patience as we try to determine the best options for our immediate future.
UPDATE: development to continue soon...
