I am still talking things over with @tempogain about what we should do with the old site. He just pointed out to me that all of our PMs were successfully transferred over from phpBB, so there doesn't seem to be any reason to allow people to login there anymore.
Here is what I am thinking of recommending to him:
1. Remove all login to /taiwan
2. I'll remove the banner zones or change them to classic 728x90 zones that will run on the top and bottom
3. Redirect traffic that goes to www.forumosa.com to automatically jump here to tw.forumosa.com
What do you think? On a scale of 1 to 5, with 1 = No, 3 = Meh, and 5 = Yes!
