Thank you for the suggestions.
We can not help a lot with this.

When a member posts a long word with no spaces, too many !'s, or similar... the shoutbox can not break the word to start a new line and forces members to "scroll" to see the complete line... members just have to put up with it till that message becomes number 30 and expires...

Different refresh times are being tested but there will always be complains about it being too short or too long...
