@kudolink:
Well, perhaps, but why spend dozens of hours - for me

- to replicate some of the features (and probably none of the hundreds of add-ons) plus test, enhance, doc, etc. rather than leverage the support of a highly creative Vanilla user community working with tuned, elegant code specialized for forums?
I’m not being sarcastic; it’s a sincere question. I think (my) life is too short (e.g., not enough incentive). I can see why others could feel incented.
Also, it is one thing to produce features; another to deliver something that ’fits’. MODx ’fits’ CMS. IMHO, Vanilla fits light-weight but powerful forum requirements to perfection. It took 100% focused development for Vanilla over two years to reach its present finished, yet early-in-its-life-cycle, shape. I don’t get the idea Paul has that kind of passion for a MODx forum or shares the same vision for it as Vanilla. No shame in that.
@zi (and kudolink)
I will gladly take a closer look at Jot (which is cool), though I don’t believe it changes the substance of the matter for me. But then I’m not a developer. Vanilla has nearly all the features you list (pre-moderation is noodling along), including the ones on the wiki - and many more. But it’s not really a feature thing per se, as I mention above.
Rolling my own ersatz forum, even if powerful, loses me the leverage I get from Vanilla’s dynamic developer and user community. And its developer is one smart and elegant hacker. Just as FYI, Mozilla will be adopting Vanilla as its developer community forum, minimally. I hear a raft of hitherto unplanned improvements already made behind the scenes may be available to all Vanilla users soon.
Net net, I still feel MODx will miss an opportunity if it doesn’t integrate. Vanilla and SMF integrations will cover between them 90% of the spectrum desired by nearly any community for forums.
