Thread:Talk:Echo (Notifications)/Mentions require signature with timestamp?/reply (5)

The signature is "only" used to (help) determine whether an edit is a new message or not. The extension checks the edit in the moment it's saved, it doesn't parse the whole talk page looking for new messages if this is what you were "afraid" of.

This was decided in the specifications: Echo_(Notifications)/Feature_requirements (I didn't make them).
