https://wiki.openttd.org/NewGRF_List
This list is freely editable by anybody who has an OpenTTD.org account. I only ask for a few basic rules:
- Do not break the Wiki table or texts. If you do not know how to edit in MediaWiki, ask myself or others to make the edit for you.
- Try to keep things neatly organized in a logical manner. Feel free to re-arrange if necessary.
- If you feel that the entire list can be organized better, use your own wiki sandbox to make those changes, then ask for others to consider it.
- Do not delete any content added. Sometimes it may just be temporarily unavailable. If it is permanently unavailable, see if it is available from another source (such as Internet Archive) and then link to it. If no other source is available, strike it out via wiki markup and make a note. This lets others know what is no longer available, and perhaps somebody else will decide to duplicate it.
- Only add content that actually has a functional release. Teasers, beta releases, etc. are fine, but don't add content that hasn't published a NewGRF or has published test releases that are known to be exceptionally buggy and/or non-functional.
