Doing? No. Have done? Yes. I've spent money on it that well exceeds the original price of it, and have spoken in big words about it on other forums (in a manner that isn't just "link discuss"). I've also mentioned it to the friends i have that could potentially be interested, but it didn't really catch on in any of them.
I also tried my damnedest in that mood icon contest yonks ago (which means that i have 32 mood icons lying around, doing nothing), although i didn't stand much of a chance against the glorious ones that Chris made, the ones you see today under your avatar. (which, honestly, are a lot better than the ones i bungled together)
Nowadays i'm mostly hanging out for the community, doing the occasional leadery thing for ORMO. I stopped being hooked about 4 years ago. :I
