Yes, finally...finished Level 3 and I'm on to Level 4.
Looking ahead to the first lesson I noticed one of the first tasks involve creating accounts on various platforms - Google+ and Pinterest - no problem there I've got those covered. In fact, since my Pinterest account became business (about a month ago) my page views went from around a 100 to over 3K.
Facebook and Twitter - that's a different story. I've had a long standing love-hate relationship with both of these and the last time I closed out those accounts I swore never again. However, I plan to create business accounts and have a more positive attitude! Realistically, I can't see having any measureable success without having a Facebook and Twitter account. The headaches these cause - well there's aspirin for that.
I can't wait to begin and learn more!
