You don't see any other commercial forum softwares who credit users/developers/graphics artists anywhere outside of the acp, do you? Including this unnecessary file as opposed to a blank index.html is just a little bit on the "weird" side... at least, it seems that way to me. Before anyone comments however.. know this:
Contrary to popular belief, I have no problem with Shelley (though she seems to have one with me), the new smilies are great, super, fantastic, lovely, albeit just a little bit girly for my tastes but that is why you left the doodle ones as an option, I get that.. Shelley deserves full credit for the smilies she has created, they're unique! Again though, the way you have done it (to me) appears a bit weird..
Your argument is going to be "well no one visits that page anyway".. My argument is; "if no one visits that page anyway, why include it, as opposed to making a "credits" page in the ACP properly accredditing Shelley for her contribution to the xenforo core, as opposed to a random index.html, which serves very little purpose." (of course, the credits page can also accredit future people who contribute to the xenforo core, as well as kier and mike)
I'm sure the least you can do to honour Shelley's contributions is to properly accredit her in some main credits area of the AdminCP of XenForo, and not in some obscure page which no one is ever going to visit..?
Of course, this is but a minor issue, but one I (me, no one else, i'm not speaking on anyone elses behalf. I felt the need to mention that as some people think that I do.) felt the need to voice my opinion on.
I hope that we can have a reasonable discussion about this, and that this post does not make me too unpopular...
