How is it done? strange

hi

there is a feature in msn mesenger 7.5 “Type your personal message here”
Once one types..and logs out after few min.. then on next login that typed message is gone..so hav to retype that personall message again

BUT

there are many people who tell that they dont retype .coz that Personal message is there as it is regardless of how many times one logins or log out..and they say they are not using any tools for that

SO how is it possible? which version does it? is it possible even on ur msn messenger?
