In WEM 8.1, we want to add helptext underneath the Channel "Name" field label, similar to the helptext under "Active State" now ("Determines whether the channel displays on your site. Your administrator determines whether the Active State field is enabled for your system.")
Our users are constantly adding special characters to the Channel Name which break the channel paths/URLs - we feel adding help text is the first step to help avoid this, field validation the next.
We've extended the Channel system object and are using property pages to add custom attributes, but it is the core Channel "Name" we want to add help text to. As it is a system object, not a CTD, we can't just add helptext like we would for field names in CTDs.
Has anyone done this and/or could offer suggestions on how best to do this?
