Here are a few tips to keep track of your blog comments:
1 Go to 'Settings' and then 'Comments'
For comment form placement, select 'full page.' Full page comment pages are so much more user-friendly than quarter-sized pages. You can read all the comments much easier, and also if you're reading another blogger's comments, you can click on a commentator and go directly to their blog to visit them. With the smaller comment pages, you can't go anywhere else from there.
2 Sign up for 'comment notification email', and be sure to include your email address. Also, go into your profile, and check the box that says "show my email address." That way, when you comment on someone's post, not only will they get an email with your message, your email address will show up, and they can reply to you if they so desire. If you omit adding your email address, your comment still shows up in their email, but the email address shows up as 'no reply,' thus they cannot reply to your comment.
3 P.S. Beautiful Mess brought up another good point in the comments here. Get rid of the 'word verification' option! Yeah, great idea, eh? That just takes up more of our valuable time. (See comments about this suggestion).
Well, that's all for now. If I come up with any more hair-brained ideas, I'll be sure to let you know.
