Here is a youtube tutorial on how to setup the Shoutbox database:
Part 1 - Style The shoutbox
Part 2 - Create a database
Part 3 - Connect The database
Part 4 - Setting up messaging (Name and Message Post)
Want me to do it, I will. However I ask $30.00 to do it for you. This can be paid to my paypal account before I set this up. You must already have access to "MyphpAdmin", and I will need access to this as well. Make sure if you ask me to do this for you that I'm using a temporary username and password. (not your primary one) This only takes about 20-30 minutes to setup.
There are NO WORD CENSORING including with this shoutbox. Post can be removed within the database found within MyphpAdmin. This is a basic shoutbox so use at your discretion.
