I posted a question a couple of days ago (in Accounts & Settings by mistake) about using the email newsletter features of addthis, by going to http://www.addthis.com/get/sharing?where=newsletter and generating the anchor tags. I was having issues adding the other properties like title and description which I think I've solved by placing & on the end of new properties except the last property.
I have a number of other questions, but I'd like to know how to find the questions *I* asked and there doesn't seem to be a users profile page as such. I got asked for a new username when I logged on today and I think I'm using the same one but a search for my username (usefuldesign) returned zero hits.
I'll also email this question to support since I may not find the answers people post here :-)
