What is a better wording for "Like / Acknowledge"?

The GIPS has a "like" or "+1" feature that conveys several things at once:

• I encountered or heard of a very similar problem before
• Thought I never experienced this myself, I acknowledge that this is a real problem
• I think that this problem is important, a solution should be researched

This helps avoiding redundant scenarios, prioritizing situations that need to be addressed, etc.

We refrained to use the more mainstream "like" terminology, since it is not appropriate for a situation that poses s threat for a patient. The current terminology "Acknowledge" may not be as easy to understand as it is. What should be a good wording for this upvoting functionality?
