Yesterday, as I was trying to update my profile signature I noticed that this new feature has been added to the forum. This is a wonderful option. I have found in the past that in case I wanted some olden posts for my blog-- I was not able to search them easily and navigating page by page was also not very easy. Now you can download the .txt file with just a click and do a simple CTRL+F to find out the relevant posts you're looking for.
Thanks Paul and Libertygrl for providing this new feature. I hope it would help current and future posters.
