From Sonic Retro
Here on Sonic Retro, he contributes to various discussions, publicises the Hacking Contest, and for a while, edited the wiki. From uploading stuff to making templates to doing minor edits, Spanner made over 2,000 edits to the wiki (and didn't even get a t-shirt for doing so!), although he's barely created pages of his own. Spanner looked at edits made and how they can be improved or fixed, before anyone else did anything. Even the smallest things would be quickly done. That is when he was bothered though, eventually he stopped editing the wiki.
Spanner's hacking efforts for a time usually revolved around importing music to the SMPS format using xm4smps, although that didn't mean he couldn't do anything else. He can do some ASM stuff, but usually others end up working with him in order to get something to work. Contributions included the music in the multi-award winning hack Sonic Boom, Sonic 1 Lunacy and Sonic ERaZor, as well as minor contributions to other hacks over the years.
He is also the user responsible for Sonic 2 Dimps Edition, a parody hack aimed at Dimps and their game Sonic the Hedgehog 4, with the hack having received mixed feedback and endless requests to add certain things. In addition, Spanner is also behind the Ben Kalough character portrayed by Skyler, when the latter was looking for a Ken Balough impersonator for a video. On an unrelated note, Spanner shares the same birthday as PACHUKA.
