Not sure if this has been suggested.

But I often find certain people deserve major props for being an inspiration and/or extremely and actively motivating members.
I know that I'd love to keep giving someone 'reps' or something similar for being such a great person to look up to for giving me such support.

I don't know how it would work exactly, and I don't think it should be something where it seems 'elitist' or anything. I just think it'd be a great idea to those who put effort in just as much as they get out of MFP.
