... oi.Safari, on a mobile device. No idea what Greasemonkey refers to in this context.
You sure you want to type out an RP on a mobile? [/is really just grouchy about having to consider mobile devices ]
Greasemonkey is an extension that exists in some browsers - FIrefox and Chrome for sure, I think IE has a version, dunno about Safari - that lets you "customize your browser experience," as the tagline goes - basically it lets you set scripts to run on certain pages and screw with the page client-side. So you could, for example, replace any BBcode tags with real HTML, to implement a somewhat shoddy BBcode parser.
