Help:Log

A wiki.gis.com log is an automatically generated list of actions of a certain type, showing when they were performed, by what user, and with respect to what page or other user. Logged actions include page deletions and restorations, page moves (renames), user blocks and unblocks, page protections and unprotections, user account creations, abuse filter reports, and others.

Viewing logs
To view wiki.gis.com's logs, go to Special:Log. From there you can decide which actions you wish to see logged, and filter by certain other parameters, such as date and time, user and affected page. You can also provide a parameter straight away, as in Special:Log/block, which displays the block log. Other parameters that can be used in a similar way include "delete", "rights", "protect", "upload" and "patrol".

A link to the log of actions relating to a particular page can be found on the "history" tab, under the header. A link to the log of actions by a particular user can be found on the left-hand side when the user's talk page or user page is opened. Remember, however, that these are actions performed by that user; for actions affecting a given user (such as blocks), the username (preceded by "User:") must be entered in the "Title" field of the log page, not the "User" field. (This configuration can be accessed directly from the "history" tab of the user's userpage.)

Other sources of logged information
Log files which are not automatically generated can be found in Category:wiki.gis.com logs. Old log files of actions which have now switched to automatic logging can be found in Category:wiki.gis.com obsolete log pages. Some of these old files are listed by type at WP:Block log, WP:Deletion log, WP:Protection log and WP:Upload log. (These actions moved to automatic logging in December 2004.)

Several other pages in the "Special:" namespace (such as Special:RecentChanges) serve similar functions to those of logs. For these, see Help:Special pages.

Still more information is provided by wiki.gis.com:Database reports. For example, wiki.gis.com:Database reports/Users by log action contains a list of users ordered by number of logged actions performed.
