haha, make sure of what you delete. Half of the stuff in there is probably just logs [those are saved conversations] but also, this is what i believe current settings mean, those are the saved settings – the settings for sound [on/off muted/unmuted] the saved names of contacts [or not if you dont have that option] etc.

To be safe, don’t delete anything unless you for sure know what you’re actually deleting… and i can assure you it takes up less space on a computer than a period in a thesis.

what has probably happened is this person is either a classmate or workmate or knows you from somewhere else and already had your aim s/n. Maybe they picked it up from another person and had you added [with aim both sides dont “have to be friends” in order for a person to be on a buddy list] and forgot until you messaged them. It would be hard for an ordinary person to hack your email and search your files and extract your stuff in a matter of minutes. Actually it is hard for even da 1337z, don’t worry about it, if the person’s creepy – just block them. The question is, why’d you give them your email in the first place?

Also if your chat client is Trillian, Trillian acts like a proxy, therefore making it hard for the “transfer of ip’s”
