yeah, hack the WYSWYG editor to add an extra button that inserts a marker (e.g. specific HTML comment) which you can replace ... WordPress has a tinyMCE hack that does something like this although in that case it's used to insert markers that allow the content to be split into multiple pages. > Personally I prefer the later options as its probably easier ;) personally I prefer the solution where there is no ad shown at all. > Regards > > Ian -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
