I am using the new release of Firestorm, and my IM chat logs are no longer being saved. I cannot find the setting to save them in the new version. Where can I change this setting back to save my IM chat logs? I went to the Privacy/General tab, and the only thing I see there is Save: Save Nearby Chat Transcript, and it gives you the option to choose location. I want to know how to save IM chat logs. They are not being saved, and I need to be able to save them. Please help!
