A few questions.

First, I read the tutorial on how to remove the "-" button on the forums but it didn't seem to work for me. I use phpBB3 and the code is:
/ *-- Removal of negative voting button in messages --* /
.vote .vote-button, .vote-no-bar {
display:none;
}
.vote .vote-button:first-child {
display:block;
}

Second, is there a way to make it so that posts stop and wrap onto the next line at a certain point. For example, make it so that the text stops just before the Quote, Edit, Etc buttons and starts over on the next line.

Third, a picture icon for an unloaded picture shows up under signatures.

Anyway to get rid of that?

I didn't see any option in the colors menu for poll question text and was wondering how that was controlled.

Last, is there a setting to control the maximum size of signatures? Again in phpBB3.

Any help would be greatly appreciated.

Any suggestions?
