I am Victoria Slinyavchook from SHAPE Services.
I have just read your review to IM+ and found it rather nice.
But this review refers to older version 3.1. Now we have version 3.4, and 3.5 is under Apple Review.
Maybe you would be interested in updating the review and adding more information about IM+.
Usually we post links to latest reviews at shapeservices.com home page (in "Recent Reviewers" block). So if you decided to update IM+ review, please let me know, we will post the link.
