I'm most definitely a newbie user to Wikipedia.
Most of the edits I make I put in the category of "slam dunks", that being edits that I would consider painfully obvious(i.e., if one entry says something that contradicts with another entry(such as the Limbo section of Afterlife) or that is offensive and POV,such as a very old entry about trachea-esophogeal fistulas(an operation I had when I was born).
I haven't progressed to the point where I would create entries or make super complicated/controversial edits.

I still mostly do edits that are "slam dunks" though I have expanded a bit. I'm planning on adding release dates when they aren't present for more obscure software titles that already have entries.
