I think it would be really nice to have the tk's implemented because from personal experience, i know they can be a very fun class (and i already have the gear stashed for one, lol)
As for the updates, it might work to upload the current kRO and skray to a download site like rapidshare, so that people could download it from there - just a thought - and i would be willing to try to set that up if it were approved.
