How do you compress reverb? Never even thought about that.

I think he means compressing a lead once it has reverb on it. I always compress my leads. Whether you put the reverb before or after the compressor is usually decided on the effect you're trying to achieve.

Oh, yes, I do compress sounds that already have reverb on them... I thought you meant compressing only the reverb 'tail'... which actually could sound kind of cool now that I think about it.

You can indeed compress the reverb (put a compressor on the FX returns, or the tracks where the reverb returns if you use that method).

If you read my reply in the sidechaining thread, here is an area where you can use it too.

Compress the reverb, but trigger the compressor with the lead/vocal/whatever you put reverb on. What happens is that you can put the reverb fairly loud in the mix. The lead plays, the reverb is "normal" in level. As soon as the lead stops playing (or dies out) the reverb tail doesn't get compressed anymore so is louder. This a way to get very lush reverb tails without drowning the lead when it's playing.

When you adjust the attack/release time you can create some weird effects too.

For example, listen to Rank 1 - Beats at Rank 1. Listen very carefully at the break when the lead is coming up (tum tum tidumdum). Listen especially to the reverb tail that comes in louder each time the lead stops playing. It creates a very pumping effect (some say too much even) if done right.
