Editing Signaturein SimplePress

I installed Simple Press some time back and then paid the 2 month subscription for access to their support forum. At the time I wanted to know how to adjust the signature size for members. I was told to make a child theme and adjust it there. I chose to adjust the main default theme and everything worked great.

Of course, you know where I’m going with this. My subscription ran out, the plugin and it’s themes have been updated and I’ve lost the notes I had about where specifically in the theme files I needed to go to adjust the sig size.

I’ve gone to SPOptions and used the input boxes there to set my sig size but nothing happens. So I’m assuming that I need to go back into the main default theme and adjust it there as well. Trouble is I can’t find where you can set width and height in pixels. After using Firebug I thought I found where it was at, went into theme CSS and it doesn’t look the same and I don’t see the parameters to adjust.

Sorry for sounding like a moron here, but I’ve run out of ideas as to what to do. Thanks for any help!
