This isn't working for me.
[sidebar_tab icon='client.png' title="Client sampling"]
[widget widget_name="avia_portfoliobox" widget_class_name="newsbox" title="Clients" count="50" cat="Clients" excerpt="show title only"]
Also, what file contains the code for the contact form? I want to change the text that says "Send us mail" above the contact input fields. I tried looking using Firebug, but it didn't show me the file name.
