Right now I use the forums I'm on and the instructional You Tube videos as my "guild."
We have one that meets in our area I just haven't had the time to go and check it out.
I have heard a lot of negative about guilds; cliquey, unfriendly or unwelcoming. But I like to form my own opinions on things so someday after I'm done homeschooling and my children have left me I think I'm going to try this one.
