I have tried many plugins in order to achieve this result on my blog. However, Thank Me Later, which you reocmmend on you best WordPress plugin list, is not working. Other solutions such as MaxWordPress Magnet subscribers and WP-Subscribers look like scams plus they need more tools to work properly, such as Mail Chimp, AWEBER and so on.
I want the chance to thank the person who posts a comment on my blog, after a couple days, so he will have the chance to go back and read all the other comments.
I am already using the ReplyMe plugin, that you guys use here, and also the Subscribe to Comments Reloaded plugin. Wordpress is version 3.4. Thanks!
