Hi, people. This is my problem: given that i've got maaany contacts, i renamed all of them so that i can remember them.

Now, if I re-install messenger plus!, or if i've got to format the computer, obviously I lose all the custom names. :/

This is my question: is there any way to export a list of my custom names? Maybe a plugin, or something like that?? Thank you for the answers.
