Many people promote their product or service using yahoo messenger or other IM method.. How can we use yahoo msgr more then 1 acct at the same time using same PC? That mean we can monitor YM chat at one time.
different tabs with diffrent email accounts and messenger accounts thenyou can have 2 chats with a different name at the same time or are you talking about for 2 people?
I really don't know how you are going to promote, But you can have multiple instances of meebo opened or use Digsby chat platform and get logged on to multiple accounts.
There's special program for that purpose, available for Yahoo! IM 8.x and 9.x you can download it from: http://www.softpedia.com/get/Internet/Chat/Instant-Messaging/Yahoo-Multi-Messenger.shtml I'd recommend you to try other (alternative) IM like Pidgin, which allows you to sign up with many accounts from 1 user interface. Pidgin supports all popular IM protocols. Download it from: http://www.pidgin.im/download/
