I also have a bit of trouble caring, but that's more about my growing disinterest with UO as a whole rather than NPF itself. Granted, NPF hasn't had much appeal to me in a long while since I feel like I "finished" it, but I'm getting more and more unimpressed with UO free shards in general. They seem to fall into one of a few categories; shards that run pre-UO:R, shards that run fully custom (read:OP as balls) RP, and shards that may have good ideas but can't attract the population to drive things. It's very difficult to find a shard that is reasonably customized/thought-out, has a skill cap, and has a decent staff and/or population. It's getting tiresome trying to find a shard that feels comfortable and isn't completely stupid.
I don't mean insult any of the shards out there; I've tinkered with different shard software over the years and I know how much time and effort goes into making something your own and implementing ideas. Lots of shards out there have some really impressive features, but on the whole just don't appeal to me.
As far as what will happen to this place, I can say for sure that I won't take it down. I've put a good bit of time into it over the years and it would be a waste to just throw away. Whether or not I'll re-design/re-purpose it into something else remains to be seen. I don't really have any game interests at the moment that are worth making a site over; I do a bit of Binding of Issac, Spelunky, and the like, but those are covered well enough by now that there's no need of it. I started this place as both a guide for new people wanting to do Mage on NPF and as an archive/thinking space for myself.
ETA: Disregard that, I'm totally going to be doing TOME stuff here. The major reason I went Mage on NPF instead of the Ninja-Whatever-Archer I intended at start was because it was the least common style of play. As it turns out, many people playing TOME seem to hate Archer. I flove it. My two winners were Archers and I have the idea of trying to get a winner with every race, so that might be something that I make a project; whether that will be here or on a similar Tome/Archer themed version of this site remains to be seen, but that's what you should expect from me in the future. If you're not already playing TOME, you should do so (unless you can't handle difficult rogue-likes).
