This is for a personal-use plugin I'm trying to make. I want to submit a comment from site A to my blog (sort of like sending trackbacks/pingbacks but a full comment).
For instance, on site A I have a form with a name, url, and comment field. The data I enter in site A, I want to submit to site B (my blog) via URL parameters or the POST method.
I assume that I'll need an action hook on my blog to retrieve data sent from site A and insert it in the wp comment table.
Is this possible?
