Gamepedia PRO is a legacy program for historically Gamepedia wikis which recognizes prolific editors with a fully ad-free experience as well as granting a special badge to users on their profile, recent changes, and other locations.
The fully ad-free experience and badge are currently limited to historically Gamepedia wikis. These wikis are Fandom wikis with the Gamepedia legacy badge in the header. See the Minecraft wiki for an example.
A replacement program which encompasses all Fandom wikis is being explored, but at the time of rollout for the Unified Consumer Experience, it was not yet developed, so Gamepedia Pro is intended to remain in place until its replacement is prepared.
Gamepedia PRO is automatically given to any user who has shown themselves to be an active editor in a given calendar month, as measured by wikipoints. Grants of PRO are given during the first week of each month for active editors in the previous month. For instance, on Tuesday May 1, 2018, PRO would be given to all active editors for the period of April 1 to April 30 2018.
When an editor earns PRO, their grant is set to last for three months and they are notified via e-mail. Editors earning PRO in successive months will have their expiration date overwritten each time. For instance, an active editor in the month of January would be given PRO lasting from February until the end of April. If they were also then active in February, their expiration date would become the end of May.
