From the File menu, choose the Publish an Edited File command. The Publish File dialog box appears. To add your own comments for a file that is under version control, you can type text into the Comments field. Click OK to publish the file. The edited file is again available on the server.
Web Publisher unlocks the file and updates the version number for files under version control.
If you have installed the Composer plug-in, opening a page in Composer causes Web Publisher to lock the file so other users cannot edit it simultaneously. Identify yourself to the server by entering your user name and password. In Composer, edit the file as usual. When you finish modifying the file, use the Composer's Publish command to put it back on the server. If you are using the plug-in, this unlocks the file in Web Publisher and assigns you as the owner of the file if it is ownerless.
