I would like to be able to filter on the idea/request email domains associated to a portal user, rather than having to pick the individual names. If I use the idea voter domains I get a list of all domains, what I would like to see is the 'Idea/request vote create domain' as an option so I can pull a list for a set of domain users that I may not know personally.
The ideas table allows for a filter on 'Idea voter email domain'. I believe this is what you were looking for. Let us know how this works for you!
