Text messages are easy to send in YAAC. At the bottom of the map window is a selector to allow to specify the recipient (either from a drop-down list of stations you have heard, or just typing a callsign-SSID in), the digipeat path to use, and the text message you want to send. Then click the SND button.
If you are going to be operating on HF, there are some things you need to do to be legally compliant.
1. Go into your beacon definition and set the Initial repeat rate to zero. Yes, zero. That means no automatic beaconing (which is prohibited in the 30-meter band by FCC regulation). If you want to send a beacon, you have to manually trigger it by pressing the BCN button on the map window toolbar, every single time you want to beacon.
2. In your Direwolf configuration file, you will have to change the modem settings to use 300 baud and a 200-Hz tone spacing. Even though the symbol rate limitation has been relaxed, that is still the convention for HF APRS. Faster modem speed will just be ignored (because no one will be listening for it), and will mark you as a lid.
More information is on WA8LMF's page on HF APRS.
Hope this helps.
