Organizational use of OBS

Hello
I'm a part of a non commercial organization, and we would like to use OBS, and specifically the virtual camera feature, for some of our meetings.
We are not sure if we are allowed to use the free version of OBS, or we need a license to use OBS. Again, we are a non commercial organization, and therefore, OBS will NOT be used for commercial use.
On beforehand, thank you for your help!

"Free version of OBS"? OBS is free software without condition. If you paid for it, you were ripped off. OBS' license is GPL. Just use it.
See Help->About->License.
