I am unable to select the 3.3.5 prefix in the support section. I believe tommy may have or is looking into (based on a previous thread) but thought I'd post it in case someone else had the issue.
You should be able to see them now, except in World of Warcraft Support -> Other.
Just tried it. I can see all the mangos/cmangos, but none for tc other then 5 and 6
Yes, Tried once before, and once just now prior to posting.
