Wanted to leave a review a few weeks ago when I was trying to install my first add-on, but I didn't know how to find the 'review' button/field until today - you have to rate it first, then the review text field appears:). Very few people could provide the same level of details as you've provided here in this tut/guide. Thanks a lot for making such diligent effort in writing this guide. It's been very helpful!
