A few questions ul#pagehistory li a[title="User:Roranoa zoro"], ul.special li a[title="User:Roranoa zoro"], table.mw-enhanced-rc td a[title="Roranoa zoro"], details a[href="/wiki/User:Roranoa zoro"],
 * Why doesn't the vector skin work?..I mean it used to work fine when I first came to know of it.
 * For some reason,none of my JS properly loads on this wiki!
 * Some users cant get into chat at all,I once experienced it on my friend's Lappy....do we have a good reason for it?
 * What does this code in my CSS do?....I'm trying to figure it out though
 * 1) WikiaRail a[href="/wiki/Roranoa zoro"],
 * 2) wikiactivity-main cite a[href="/wiki/Roranoa zoro"] {font-weight:bold !important;}


 * I tried editing Runescape wiki,and found that we can have standard edit summaries,can anyone gimme the code that can be used on the Personal JS?
 * Thanks!
