Add this integration

Add This Integration is complete -- a few funny caveats.......

Facebook share will not preview images with spacing in them. Which is quite a few images. The click through page will still show the correct image, but the previews will suck. A share with a correct image is attached.

When sharing via email, the email template does not show in the share UI, however the emails come through with the correct message. This is a known bug in AddThis and gets several complaints. Not much we can change about it. See attachments.

Url shortening currently only works for Twitter and is linked with our existing Bit.ly account. Twitter templates to specify order of vars is currently broken, also a known AddThis issue. 

Seen an odd/intermittent issue where sometimes the Pinterest button opens a Tumblr share? Saw it once yesterday and one early today, but have not been able to replicate it since. 

Button positioning confirmed in Chrome, FF and IE 10.
