1)Please have preview be something that you have to turn on to use, rather than have to turn off to post.

2)I liked the feature where you could see everyone's status, but I don't know what it was called. It would show the activity status of everyone online.

3) The light and dark purple tones do make it hard to read for me, (I have a really dark monitor), but I don't know if "hard to read" is considered affecting the usefulness of the site for everyone, if it's just me. Just thought I would mention that it does affect readability for me.

I can't think of anything else right now, but if I do, I'll edit and add them here.
