I do not think removing subSilver, really the worst phpBB template is prosilver it was my first template and I do not really taste it is messy when you try to design a prosilver based skin, just change some things and the main characteristics of prosilver left, making haiga not no comparison
But not the point of discussion for me is the best subsilver2 created phpBB template as it is 100% customizable and I know many forums that their forums are based on subsilver2, are too sophisticated. Actually, I think you want to eliminate subsilver2 only because it is difficult to create MODs, if this is so hard for this MOD team, which must be professional in creating MOD for phpBB3 two templates available, but I will make If many users are able to switch to software.
But I mean I had read in this thread that would be a good choice subsilver3, but I feel great but subsilver3 want to call it, call it in honor of phpBB 3.1.x nickname, I have an idea as Ascar .. Subsilver3 also want to suggest that if developed and accepted by the team of developers, is sophisticated, customizable and subsilver2 and do not miss the organization. Since subsilver2 is much better for large or important because the information is well organized, not that I personally prosilver is very messy.
