Oh, one more thing. You'll need a passcode to successfully beacon from APRSIS32. You can use the same passcode that you have from your APRSISCE for Windows Mobile or any other APRS-IS client that you use.
If you don't have a passcode for your callsign (-SSID doesn't matter), drop me a private e-mail and I'll send you one!
