is there anyway that you can make plus not save all the logs you have? i have tried to look on preferrences but it doesnt say anything about un-saving on there, and so the furthest ive got is putting a password on them....please help! my computer gets so clogged up otherwise!

You can choose not to save log files by default by going to Plus! > Preferences > Logging and unchecking the first option.

You can (un)check this option for each conversation in the Plus! menu in a conversation window, and you can simply delete log files that have already been made to get rid of them
