This is a project I've been meaning to get to for awhile, but I figured I'd open up a brainstorming session for it (everyone is welcome to post ideas, thoughts, things you've tried). Christine had "requested" a script where you could "subscribe" to comments… ie. you leave a comment on someone's site, but you don't want to have to keep going back to the comments section of that one post to see if anyone else replied. You'd just get an email (kind of like the one MT sends the author) that says – new comment – maybe it even HAS the comments in it…
So my original plan of attack was…
to take a look at mt-comments.cgi. See what makes it email comments when a comment is posted. Maybe capture email addresses on the comments form (from people who want to subscribe to the comments) and make an array (in an external "flat file") of the email addresses – and when the comment is mailed to the author, have it also mailed to the mailing list (in that array)
Anyway – those are just my initial thoughts/plans of attack. Probably won't get to seriously play around with this until this weekend – but thought I'd open it up for anyone who's up for the challenge.
