When editing an article on Ireland Information Guide there is a small field labelled "Edit summary" under the main edit-box. It looks like this:

The text written here, up to 200 characters, will appear on the Recent changes page, in the page revision history, on the diff page, and in the watchlists of users who are watching that article. See MediaWiki User's Guide: Edit summary for full information on this feature.

Guidelines

Always fill the summary field is one of Ireland Information Guide's guidelines. Even a short summary is better than no summary. Accurate summaries help people decide whether it is worthwhile for them to check a change. Summaries often pique the interest of Ireland Information Guide users with an expertise in the area. This may not be as necessary for "minor changes", but (e.g.) "fixed spelling" would be nice even then.

When uploading an image one should supply an upload summary. Please see Ireland Information Guide:Image description page for full information on this feature.
