Nope - the owners of the site just want it to continue to be a great resource for property investors. That was their goal when they started it, that still is their goal now.
I disagree. IPB is good - but I don't think there is a need to migrate off vB, it does everything we need it to and is extremely extensible (have a look at what I've been able to make it to on ZooChat for some examples:
http://www.zoochat.com/ ). We really aren't using the capabilities of vB to their full extent at this point. I am planning a redesign of the site sometime down the track to take better advantage of what this software has to offer in the latest versions.
Jan and Ian have made it clear that they would prefer to maintain their independence and not rely on sponsorship or advertising. Advertising isn't the only business model available.
Moderators come and go. It is a volunteer position and I think the moderators we have do a great job. We do ask new people to join the team from time to time.
Jan and Ian have made it clear that they want to focus exclusively on real estate. We tolerate discussion of shares and managed funds in the off-topic area (Coffee Lounge), but would prefer people focus on property. There are plenty of other discussion forums out there which cover shares and managed funds.
The coffee lounge already does allow you talk about just about anything except where it goes against the forum rules or covers one of the few taboo topics we have on this site because (from nearly 10 years of experience on this site) they always end up breaking the forum rules.
