Submitting to a few site i scrapped

Hi, I was wondering if i have a list of lets say 40 forums websites and i want to automate this with GSA. How can i submit to those 40 site only. Do i just uncheck all search engines to use and then import target urls? Thanks for the help!

correct, but make sure you enable "forum post" as link type in project options.

Thanks @Sven Is there any way to add an engine or can I only use the ones provided. 

you can always add new engines using the script manual (see http://docu.gsa-online.de)
