Here's an idea for those who are adept at coding.
Server maps can get quite large and detailed with so many folks building. It may be helpful to have a list of interesting places... a tourist guide of sorts... that everyone on the server could access.
Mauvebic wrote a handy mod called "Bookmarks" (the lastest version is packaged in the "Riventest" mod http://minetest.net/forum/viewtopic.php?id=2399). This mod creates a file called "bookmarks.go" in the /worlds folder. In this file are all the locations set, in-game, by the user (or added with to the file with a text editor). Typing "/listgo" in the F10-console or chat produces a list of locations and their coordinates. Then all a player has to do is type in "/go <locationname>", ie: "/go camelot" and they are teleported to "Camelot" on the map.
Now, in a server you may not want everyone freely adding bookmarks to the main list. That's where a coder would have to come in and adapt Mauvebic's code (or maybe it is something as simple as setting the read-write-execute file permissions to bookmarks.go) so as to limit write access to admins only.
I've observed on the "Servers" forum, player usually have to ask for "interact" or "build" privileges and provide their in-game nickname on each respective server thread.
Perhaps by using this protocol, players could submit to the moderator/admin of the thread/server for concideration, the title and coordinates of what they would like added to the main location list.
It would also be useful for people looking for a server to join if they could, by default, access this list and be able to teleport to those locations even without "interact"/"build" privs. A way of taking the grand tour of the server map without having to aimlessly wander around for long periods of time.
Thanks.
