FEEDBACK REQUESTED: do you want a 'forum' social media icon?

[cellarius]

I see the need, and would support the idea.

Actually, I like #1 least. I find it to be somewhat meaningless. It looks like any text anywhere whit an image in it. There's no representation of forum discussons in it, somthing #2 and #3 capture better in my opinion.

I would prefer #2. I see the scalability issue with the smallest size, though. But if you look at other social icons and how they scale to that minimum size, it really is not that bad.
