Who is InfoPop's target client for UBBThreads? Same or different than the target client for UBB?
Why would the product be called Ultimate Bulletin Board Threads? If you're going to change the name, why not think up something completely different that will make it clear to everyone that it is in fact a completely different product than UBB. I think you're going to shoot down a lot of potential customers who don't like UBB or anything InfoPop puts out (many of the W3T users are of that opinion, from what I've gathered over the past few years) if you call it simply 'UBBThreads'. If the name of the product is the first impression on a potential customer, and they don't like UBB, they're probably not even going to want to hear your pitch, as the name UBBThreads suggests (to me anyway) that it's a product similar to UBB.
This is another example of the differences we fear. If a name were to be chosen for W3T, I'm pretty sure Scream would ask users to make suggestions, we'd vote on it, etc. Would you be prepared to take user suggestions or allow users to vote on a name for the forum? While you and Scream would have the final say (just as Scream would in the past), it would let you know what the people who are actually going to buy your product want to see it called. Many of us run our own websites and web businesses, and together we can understand issues relating to forums as well as any corporate strategy team.
Like I said, user input along with Scream's superlative technical skills is what made W3T what it is. We'd hate to see half of that get chopped off when InfoPop is at the helm.
