This is really me complaining about carriage returns again more than rich text, but I never got anywhere with that so starting new (with a poll because that gets you views!).
I really need to be able to create new lines in comments. Bold and links would be great, embedding pictures and YouTube videos would be even better. Why do I care so much? Because the comment system is how GTN is looking for us to create solutions (based on the new badge names & descriptions), but if all we are limited to a paragraph of text this is going to hold the solutions back. We need to be able to create lists or multipagraph solutions.
Well, I think anything improving the formatting of the site, making it more readable is a positive. The only reason I don't use the forums at Achievement Hounds is that they are just a jumbled mess of text, and are completely unreadable.
I love this idea actually, I'd like to see something more like FB integration and or maybe away to post our comment to FB more easily. I just wouldn't want GTN to end up looking like Myspace or something.
