XP tracker

The XP Counter or Experience Counter was originally released by Jagex to members along with the Bonus XP Weekend on 12 March, 2010. Exactly a month later, the XP Counter was released on 12 April, 2010 to all players. This counter is located directly under the compass and to the left of the minimap. It didn't get very much attention because it was displayed on the same announcement that unveiled the much-anticipated skill, Dungeoneering. The icon for the XP Counter was originally a circle with "XP+". On 13 April, 2010, (a day after the main release) the XP Counter icon was changed slightly and the "XP+" was simply changed to "XP".

Function
The XP Counter is opened by either left-clicking on the counter button or by right-clicking the button and then choosing "Toggle XP Total". When opened, a small box to the left of the icon will appear; the counter. It counts the amount of experience a player has received since they last reset it. Logging in or out does not affect the counter whatsoever. Every time a player has the counter out and receives experience (from any skill), experience is added to the count and a small ribbon and the amount of experience they have just received slides down the right side of the screen. To reset the counter, right-click the XP Counter button and choose "Reset XP Total".

Trivia

 * Jagex originally had no priority to release the counter, but many players made threads on the official RuneScape forums for the XP Counter to remain after the Bonus XP weekend. Jagex then confirmed that they would look into releasing the feature.
 * Before 25 May, 2010, the Alt Text, when the mouse was hovering over the XP counter icon, was "Click". This did not tell anything useful about the XP Counter itself. Other buttons have more informative Alt Text, such as "World Map" and "Turn run mode on". Afterwards, the text was changed to "Open XP Total", and even later on, "Toggle XP Total."
 * The XP Counter's font does not match RuneScape's font. This is most apparent with the "0"s.
 * The reset option used to be very frustrating to most players because it could easily be reset without intention. A left-click on the XP total box would clear the counter. In response to this, on 25 May 2010 Jagex fixed the XP Counter reset button and made it so that a player has to right-click the XP Counter button and choose "Reset XP Total".
 * The allotted space for the XP Counter seems to only be 8 digits. However, if a player receives over 99,999,999 experience, the ninth digit is placed over the colon, near the right side of the "P".
 * When the experience on the counter reaches over 214,748,364 experience, the counter will display the word "Lots!" in red letters. A higher number cannot be shown because RuneScape uses 32-bit signed integers, which cannot store numbers higher than 2,147,483,647. Since experience is stored to the tenth of an experience point, the maximum experience on the counter is 10 times less than this.
 * After lagging, the experience earned shown on the ribbon might merge and show the combined experience earned for the period of the lag, instead of showing separate ribbons with experience.
 * On 25 August 2010, the font for the XP Counter was updated.
