When looking at the main page and most recent posts it would be nice if any post in the new member forum was a different color or stood out from the rest in some way.
This would help accomplish two things:
1) New posts would stand out and we could welcome them accordingly.
2) New posts would stand out and we would better avoid general shenanigans and douchebaggery in said posts.
I have found myself carrying my sarcasm over to new members posts not realizing they are in the new members area. Maybe just the names of the forum the post is located in could be color coded in some way?
