It would be really useful if this plugin could be used as replacement for the WP comments function to allow visitors the choice to post a public comment or send a private message per entry.
For example, a visitor is viewing my 'Hello World' post. The comments section would look as usual except the visitor would see buttons for "Post Comment" and "Contact Author". If he selects "Post Comment" his comments would be submitted in the normal way to WP and appear in the post. If he selects "Contact Author" his message would be processed by your contact plugin and not appear in the comments.
Other helpful features would include:
Option to set default as "Post Comment" or "Contact Author"
Where multiple authors exist on a site the author of the post is contacted
Easy plug and play replacement of default WP comments with cforms Comment or Contact
That's a great thought, I'll look into it. I do know that there are at least two users in this forum who are using the current release to do what you're looking for (with a bit of customization)...
