We all understand how Finale Notepad, the only free version people have access of the software, is very limited with what it can do, and requires outside help from people who own the full version to implement things they cannot do. Musescore, on the other hand, has features and customization that matches the full priced version of Finale, and it's also free. Not to mention that for some people, it's easier to use than Finale's software library.
Now, I get that the format system we have has been around for years, and I agree that previous formats shouldn't be changed. I just think that for those who don't have the means to get Finale or want to deal with the limits of Notepad, there should be an alternative formatting thread made for submissions that allow people to submit Musescore renditions.
Musescore has the ability to basically do most, if not all of the "guidelines" that the current format requires. Title with a subtitle for the game, listing the arranger and composer, having the copyright while including the site's URL, this can all be done with Musescore, maybe with a little more effort involved, but it would still be possible for basically the same format.
Now for submissions, we could replace the .musx format option with Musescore's .mscz format, or alternatively add a .xml or .mxl format (which both finale and musescore can access and create), in which the .mus format can become optional.
We do have a bunch of ways where this possibility can work, I believe, so that is why I'm making this thread here. It would make submittor's lives easier, it would make it easier for updaters to not deal with recreating people's submissions or basically do the writing for them during their free time, and it would make this site more accessible for arrangers.
Hope this could be considered, -PlayfulPiano
