Thumbs Up Limit?

[Nuggetirl]

I was perusing the calendar contest thread and thumbs upping pictures that I liked when it suddenly greyed out and I couldn't do it any more.

Is there a limit? It's carried over onto other threads I'm looking at now.

You have a .limit of 10 "thumbs up" per day..

.GFM's 20 per day...
