for some reason it wouldnt let me edit my last reply so this is what i was going to add.

i just read the shout-box area on your website. there are a couple shout-out boxes that do not need php/mysql, some run on txt databases. there are also a couple website that host free shout boxes, sometimes with a small text link somewhere. some host give you a nice cp to change the colors/font of your box and also has ip bans and word filters too.
