Searchable PMs

[Senza]

I think it might be of use to have the search function allow you to search within your own PM inbox. I know as an admin, I have thousands of PMs that I keep, and when trying to find an old PM for a particular piece of information, a search function would be of use.

I've done my best to search the site as to avoid a duplicate request, and have seen nothing.

Thank you.
