Winmx pm uses UDP protocol, its unreliable and after 2 years of saying "I can't pm you""did you get my pm"on Winmx I can't stand it anymore so I do this - join 1 good open nap network through Winmx with alll your friends/join a channel and add each other to hotlist. You can leave the room/log off/reboot/disconnect , it doesnt matter. If you don't change your names, your friends will show up as online in a permanant hotlist as soon as you log onto the network and the pm is TCP protocol, works good just like a real messenger inside your winmx
For those who don't know how to open nap thru winmx, go to the winmx networks tab and press the OpenNap Protocol Networks button and press the add button, I use
You need 500 files totalling 1.2gb or more to use RockMep2p and child porn/rape/incest filenames are banned. If you register your name on the server, no-one else can use it on the network so create a login name and password and tick the Register username on next login when you are ready,,, press ok, hilite it in the server window and press the connect button.
Go to winmx chat tab and press the List Channels button/select RockMep2p and fetch list. Join channel #hotlist or find each other thru filesearch and put each other on hotlist.
This method is working out good for me, i don't have any yahoo,msn,aim,icq network messengers and now i don't have to be in a chatroom to see my friends online or spend 70 seconds watching a winmx msg try to send.
