I went to WY with a guy this year that I met off another forum that is from my state. It went great, however I made sure he knew things about me up front and he did the same. We also did a couple fishing/turkey hunting trips to make sure things would jive between us. We have established a friendship and I feel very fortunate.
It is hard to find someone that has the flexibility as I do, let alone the passion/style I have for hunting and the outdoors, but if I meet someone on another forum that wanted to hunt I would give it a try in a heartbeat.
Some of my best friends and hunting buddies here in TN would likely become my worse enemies if we went on a couple week Western hunt together, actually I do not hunt with one of my best friends anymore because our two styles do not mix well. So its tricky to find a good hunting partner and if it takes a online forum to do so then I have no problem with it.
