It was not hard to find some teams which I wanted to be part of.
Winnipeg Etsy Street Team
First, I live in Winnipeg. So naturally I wondered if there was a Winnipeg Team. There is! It's called W.E.S.T, "Winnipeg Etsy Street Team." This team is definitely the most active of the teams of which I am a part of. Makes sense too, since these are people right in my area. The team forum has lots of helpful information that matter to me as a Manitoban. I can ask about shipping from not only Canada, but Manitoba as well. There are lots of information about local craft shows (way too much for me to think about right now). Also the teams meets together once a month. I'm looking forward to the March meeting, as that will be my first.
Bookbinding Etsy Street Team
Another Team that I am a part of is BEST, "Bookbinding Etsy Street Team". This is actually one blog I stumbled on a few times long before even thinking about selling on Etsy. Originally I browsed the blog for great bookbinding tutorials. This a great place for meeting other bookbinders. Among other things, Best regularly hosts book swaps for it's members for those who wish to take part.
Etsy For Charity
Etsy store, this team was a natural choice.
What else does a team do?
Teams are also a great way to get you motivated to try something new. For example WEST just listed it's March Design Challenge to it's members. From that challenge, an idea sparked for a new design (soon to be posted), one which I am doubtful if I would've come up with otherwise.
I also find it a lot more comfortable asking members of my fellow team questions as I'm not just asking a general void. I can ask specific questions in a more relevant circle (eg. shipping a book from the Bookbinder Team, or shipping from Winnipeg from the WEST Team).
You can also shop by team. Team members tag items with their team name making their items easy to find by other team members or sellers. As a seller, if you wanted to buy something specifically that would help a charity you would search for "etsyforcharity" and the items from that team would come up.
It's also a way to support other team members. Creating treasuries from team members items are a great way to get their product noticed more. Tips are given from other team members, and often teams have threads showing off new items.
So if you have an Etsy store or are thinking about opening one, check out the teams. There are a lot of them so take your time thinking about which one(s) you want to join. You don't need to join them all (that's over 4000!) and you don't need to be a member to view much of the threads in the team forum. For me three was a good amount to be part of. But as I say, check it out!
