I understand the nuclear color . i just took a second look it seems that i judged it too fast. The background seems now good, maybe my mood was playing its turn back then .
I still insist that it would be better for you to remove that register now banner, because it is distorting the background , you understand what i mean? It would be better if the green is just enveloping the forum without a centered green color. Although it is not that bad.
Any ways,good luck ! Choose which is the best.
