Don't know what word to use?
Use "Interface". I just did.
I was thinking of an NRI thingammajig, and I didn't know what word to use: meeting, association, joint-effort, interaction, conclave, seminar, conference, etc. but nothing worked.
So I used "NRI Interface" and "wow" suddenly I come out looking erudite, knowledgeable, uppity, modern, progressive, whatever.
Lesson learnt: use "Interface" gratuitously. It's a nice word, it will fit any description.
