Hey I'm Dan. I generally just make minor edits to fix up inconsistencies I notice around the wiki. I'm not an expert on wiki-ing or OSRS but I try to help out here and there with small stuff.
I have a page with helpful links and projects I'm tracking at User:BigDiesel2m/ProjectList.
If I'm working on something it's probably somewhere in User:BigDiesel2m/Projects.
