So, I totally approve the idea of "official projects" and I kinda dig the idea of uploading sheets for an entire game OST at one go...but something tells me that it'd be better if official projects got their main site updates at regular intervals or something.
Short version: I think it'd make more sense to have monthly/some interval updates for official projects.
This is all from my point of view, haha.
I think the main site is a fantastic platform for browsing sheets. It's simple and intuitive. I remember that I checked up the site once in a while for site updates once in a while just to see if -that sheet- from -that game- popped up. A Google search would have solved it, but if there were accepted-and-ready sheets on official projects on the forums I probably wouldn't have found them. Plus, I kinda wanted PDFs then, sp the raw mus files didn't mean much.
Fast forward a little, I got interested in the Undertale OST and I kinda wanted to browse through for nice sheets on the main site, but none of the new ones were up yet...and that's for a project with - I assume - pretty high demand from non-members.
From a business point of view, it makes sense to do an update once in a while just for these official projects, I think - something like "here are some accepted sheets from X project, expect more to come!" can really draw in non-members to the site. It helps even more if the updates are at consistent intervals (months are nice) because people tend to like consistency. In simplicity, releasing OST sheets in intervals can build hype and build our audience
Though, I'm assuming that NSM wants more members; perhaps that isn't the case, because more members doesn't translate to more quality arrangements - or to be more blunt, quality arrangers. Building hype can draw in people who aren't really that into the whole arranging art and NSM becomes more of a community-building site than a semi-professional online publishing house.
That, and maybe it's infinitely easier for the updaters to just do it all at once, haha. Confirm that for me? ^^;
Anyway, fun suggestion to rope in a little more non-members. We're currently doing Undertale and Pokemon DPPt, and those are pretty popular games with decent demand for good arrangements. Think now's a pretty good time to build some hype~
