Yeah it's weird. In the last week the default text colour has become white; I don't know if it's part of the new skin? Any admins who read this, could that be adjusted?
If you click the fourth box along the top of your post (the A with a line underneath) it gives you colour options. Click the black option (or whatever colour you want) and then start typing. You'll be able to see what you're doing then.
When you make a post the forum adds the date and time that it was posted to the bottom of the post. The edit and delete buttons are right next to that, just in white text. So highlight that area and you'll see them.
