Mercury Messenger can do the same things as your normal messenger:
  • Talk to friends
  • Change your nickname and status
  • Add a display picture (also known as an avatar)
But Mercury Messenger has some extra functions that your normal messenger doesn't have, for example:
  • Be online with several MSN adresses at the same time.
  • Login with your status on 'Invisible' or any other status you want.
  • Have a different MSN name in every conversation
  • Use and create your own plugins
  • Default plugin added: a FileServer for MSN using IRC like commands
  • See when someone starts a more...

Well is this the end of Mercury Messenger for Mac? The developers site Mercury.im now just gives a link to the Android market place. Where of course, you only find an android version of Mercury now. (sic) No good bye, no thanks for your support through the years, Nada. It would have been nice if the MSNP16 or 18 protocol would have been stabilized before shutting down. I'm guessing this was the last build:
2.0 RC7-5

At least Danny didn't try to stick us with a $5 fee.
Good luck anyway Danny.

I have Snow Leopard and Adium is being a bitch, doesn't let me add some contacts Some friends do get my messages but can't reply. Trillian is THE SAME. This program works very well, no crash and it's very effective, but the inter phase is VERY UGLY if you're used to Adium, you will think it is very old fashion PC. And it doesn't combine your contacts from different accounts, it opens several acccounts but separate the contacts by tabs, not nice if you wanna keep an eye on all of them at the same time.

The same here.
I am no working with Microsoft Messenger.
men what annouing.


There is an update to 1.9.5 on the website that should alleviate the problem. Everyone I know on MSN Messenger/WLM and work-alikes such as Mercury Messenger are having a lot of disconnections.

This seems to be the only client that supports legacy MSN Messenger video as well as Asian languages. Adium doesn't support video and aMSN didn't support Asian languages the last time I tried it. Microsoft Messenger will be supporting video the next time round, as they're waiting for the Windows version to catch up.

This is a good client. It works reasonably well at all times. CPU usage seems reasonable finally and it's able to be themed so it can take on other look-and-feel skins, including the Mac OS X look-and-feel.

I've used it to connect to a number of MSN Messenger/Live Messenger clients and it always seems to do okay but it's not spectacular. Version 2.0 is being developed at the current time.

Wow, 1.9 is Great. Gone are the bugs from 1.8 and the interrupted video chats. The new logo is very nice. I wish It had it as the new logo showing in the opening progress bar too. I really don't know what the others are talking about regarding CPU use. I have it open on a G4 1.5Ghz. Powerbook. My activity is 4.5% to 8.3% and only ~10.3% with the Emoticons panel open. I'm moving back to Mercury from aMSN. At least untill Adium gets video. Thanks, guys for a great product.
