Please, Burnside, Please, please please send this information out as an email to all btct users. If there is anybody who does not check these forums often they might not realize anything is going on. Why was the announcement not sent as an email in the first place?
I'll explain my thought process on why this hasn't been a higher priority.
1) It's going to take a bunch of time.
2) If you're not checking the forums or the site for days at a time, then you're probably holding what you have for a reason and whatever that underlying reason is shouldn't change just because the asset is going to have to trade on another exchange other than btct.co.
3) Almost all of the issuers have made a notification or two, meaning, their asset holders have received an email, meaning that the majority of the site users have received notice, just not from me directly.
4) I know it's somewhat counter-intuitive, but the users discovering this gradually is better for the panic situation. A situation which I believe to be far more destructive to the type of person who doesn't check up on the site daily.
I hope that makes sense. With that in mind, it is on the todo list and now that the withdrawal requests are dwindling I can probably code it up in the next day or two. I do want to make sure everyone gets their coins out before the end of October. Having to refund via forced withdrawal scares me a bit. You never know if the address on file is still good or not.
