+    <b>My database has an underscore in it's name, and when I grant privileges
+       to a user for this database, a backslash is added before the underscore.
+    </b><br />
+    This is normal and means that the grant is done only for this database. If
+    there was no backslash, this would be a wildcard grant, and the 
+    underscore would mean &quot;any character&quot;. So, if the database name
+    is &quot;john_db&quot;, the user would get rights to john1db, john2db...
+    instead of just john_db.<br /><br />
+    If you really want to grant using a wildcard, there is a dialog box &quot;
+    Database (wildcards allowed)&quot; for this.
