Hey, I did stuff too :P....
Official = the team maintains and supports it ;)Honestly, I suck at providing support and updates for my plugins and mods, so I try and make it fairly feature complete at first so that I don't have to do much to maintain it. For the same reason I'm afraid of it being an official plugin, not that I mind it being one.
If you want, of course!
I think I did a good job of maintaining and supporting your SMF Media Gallery ;)
Ofcourse, I'd love that.
