Mostly I just make small copyedits. Often I don't bother logging in to make them, because I'm lazy like that.
For instance, this is my current IP number.151.202.111.202 21:40, 13 December 2006 (UTC)
And today, I'm using this one (it's a university number, though, that many people use because most editors work for universities and have no life). 129.98.208.142 05:49, 27 December 2006 (UTC)
This is also me70.19.167.239 06:42, 2 January 2007 (UTC)
