So there are online forums for whatever your interest is, as well as for many of the online selling venues. The good news is it's a place to socilaize, learn tip and tricks, technique, sources for things, just a wealth of information.
The Bad News is that you will pretty much always find someone complaining about something. I have decided that this is their bag and to not let any of that influence my thinking in any way. We all have our own experiences and sometimes it's a thing where people would rather complain about things than do something about it. There are so many good resources out there, it just bugs me, you know!
Enjoy your time on the forums, just know there will be those folks that don't get all they can out of it, but I know YOU will :-)
