Your forums are hard to read. If you make the following slight changes, it will make them so much easier to navigate and follow:
-Change the main background to white or any color that is not the same color as the dividing line between the topics/replies. This will also mean you can see the buttons now.
-Change the header color to something darker to stand out a little more.
-Change the color of the fields in the new post section to be lighter where the text fields are. You cant see them.
-Move the logo down 5px to center it.
-Change the "welcome to glowforge’ composer-pop up on new posts to not be black and brown. this is pretty hard to read too.
Ive created a replacement style using the stylish plugin for browsers that will show things a more legibly. All you have to do is install stylish and use the theme for this site.
Hopefully they will clean it up a little so you can distinguish between buttons and fields and different posts.
Love the glowforge btw. Im pretty sure I covered the entire internet in links! ha
