In case I'm the artee you're talking about, not sure what I've done to deserve thanks, on the other hand, I guess fair is fair, I can also not thank anyone... :-)

BTW I just found this thread because I was trying to figure out where the Thanks button would be...

And also, I did indeed change my email address recently, but I have since used the activation codes sent to my new address to confirm it.

[edit] I just redid the activation via the link in the mentioned ticket, and it should be ok now. At least I can now thank.
