Okay, Dolby has added the WotLK flag. It is *
off* by default, for now. But it does mean that you can tag your "live" addons as being WotLK compatible as well.
[edit] In addition, Dolby has added some code so that there is a link at the top of the WotLK Beta download category that links to any "live" addons that have been flagged for WotLK. So now if you have a "live" version that works for both live and WotLK, you don't
have to have it in both categories seperately. If you still want to have a seperate version in the WotLK Beta though, because they still need testing or whatever, you are certainly welcome to.
