Normally we don't include business items here on the blog but this problem warrants a mention.
Our apologies for those who have tried to join the Urban Sketchers Seattle Google Group recently. See box in right margin. We, the Admins, have just realized the function seems to be broken. You may email usk.seattle at gmail.com (making the change to an "@" sign) to request one of us add you directly from our end.
This Google mail group is how we communicate with our members. Members may also initiate messages. Despite the "join" function being broken, the email group still works.
Image inserted for interest: it's not a computer, it's a microfilm reader, but you get the idea.
