If you have an honest, helpful testimonial or review of something purchased (or won on Facebook) from this site, then by all means, write it. If you have something to sell or other non-related spam-type nonsense, expect it to be deleted.
The best reviews are the ones that are not only good, but also offer ideas to learn from. I won’t hide a negative review if there’s something to learn from it. I’m not going to keep reviews that say something like “You shouldn’t be lazy and using 3D, you should draw it by hand!” There’s nothing to learn from that besides the ignorance of the poster. It’s faster to use, yes, but certainly not lazier. That argument’s best saved for those who know and understand the medium. If you haven’t used it, you have no right to call it lazy or even bash it.
I also won’t keep testimonials that are openly hateful. If you’re going to bash my work, expect to be banned. I have a low tolerance for the “I hate 3D” type posts.
Posts that say something along the lines of “I loved this book, but if you had changed the camera angle on page ____, panel ___ to ____ it would have been even better!” There’s something to learn there. A lesson that can be used in future books. Of course, if you want to simply say “I LOVED THIS!!!” That’s good too!
Keep everything polite. Even the “I #*$&%*^ loved this!!” kind of posts. Remember, this is an all-ages friendly site and swearing – even to emphasize how much you like something – isn’t necessarily a good thing.
Keep it honest, but keep it helpful! I look forward to lots of delightful and educational testimonials and reviews!
