A friend of mine asked me a while back why you can post comments on some blogs and they show up right away, others say they're waiting for moderation, and still others require you to type in some magic password for your comment to appear.
I had never given much thought to it. I wasn't concerned enough over spam or, worse... haters, that I want to be emailed every time someone leaves a comment so that I can approve it. I like to think my target audience is mature enough not to leave a comment saying simply "Sam sucks!!!" (And if you're going to, at least tell me WHY I suck! Be constructive with your feedback.)
In order to view and change the various options that Blogger offers in regards to comments, head to your dashboard (or posting area) in Blogger and click on Settings, then on your Settings page click Comments in the menu right below that.
Now you'll see a whole page of stuff! Soooo many options! :)
First option is to show or hide comments. Pretty intuitive what that's all about.
Second: Who can comment? Again the options are pretty intuitive.
I am not sure which Blogger defaults to, but I know that I had to go in and change it to allow for anonymous comments. A friend of mine had tried to comment and couldn't- so if you want your blog open to comments from anyone and everyone, click the first option, "Anyone: includes anonymous users."
I'll skip ahead to Comment Form Message. This is just the message that shows up above the box in which readers comment. Most people write a quick sentence saying hello to their readers or encouraging them to leave a comment, etc. This only shows up when the reader clicks "Leave a comment" or clicks to read existing comments.
Below that you see Comment Moderation. Here's the one most bloggers are primarily concerned with. Your options are: Always, Only on posts older than # (the default is 14) days, or Never. I've always left mine on Never, but apparently Blogger will notify you via your dashboard if you've got comments waiting for approval. They also give you the option to be emailed when you receive an anonymous comment.
After some consideration while writing this post, I'm actually going to change my comment moderation to Comments on posts older than 7 days. I always feel bad when I go back to a really old post and see comments on there that were left months ago, and I had no idea. This way hopefully I can respond to everyone if they have questions about something.
The option immediately following this is Show word verification for comments? Simply yes or no. I guess this prevents spam-bots from attacking or leaving upperdeckers on your blog. Mine was defaulted to Yes but I'll change it to No and see how it goes. I hate typing in those words!
Then you can choose whether or not to show profile images next to comments, and lastly you can enter your email address so when you get comments for approval- if you choose that option- you will get an email (and probably a notification on your dashboard too).
