I used aidum for a while and then changed to the msn for mac. Today I decided to use adium again, and when it opened a lot of pop up windows appeared saying I though it may have something to do with the changes I made on my contact groups while using the msn, so I continuously clicked yes. Suddenly I saw that one of the mails belonged to a person I had deleted (but not blocked) from my contacts a while ago. Does this mean she will appear again on my list? And if this person blocked me or something, will she receive a request from me to add me again? Thanks!
