[rake]

getthat,
within your phrase manager in the admincp, try adding your phrase (adv_portal_removelink) to the global phrasegroup. see if it works then.

If you want to add your own separate phrasetype, for whatever purpose, you need to run two queries:
INSERT INTO `phrasetype` VALUES ('id_here', 'varname', 'Name', 3);
ALTER TABLE `language` ADD `phrasegroup_varname` MEDIUMTEXT NOT NULL ;

the id has to be under 1000. You can then use it within your pages by adding varname to the $phrasegroups array at the top of the file.
