Is there any way to give commenters the ability to subscribe to certain comment threads? I didn’t find anything in the FAQ or forums so I’m assuming the answer is no. Are there any plans to implement this in the future?
if the commenters have IDs associated with your blog, then they can modify what they subscribe to. they login and under profile – they select subscriptions – and pick the tags that they want to subscribe to. i’ve got help page on one of my sites that shows how to do it, you can check it out here.
