#### Change the limit of 300 annotations per page
In BigBlueButton 2.6 we introduced a cap for how many annotations can be added to a single whiteboard (slide). The default value is set to 300. The reason for this cap is that when a large number of annotations was added, it was often times done in the case of multi user whiteboard being enabled and a student trying to be funny. This had a negative effect on other participants in the session, specifically on limited CPU devices. In almost all cases we observed during the testing phase of BigBlueButton 2.6 this cap was sufficient for the normal run of classes. In very rare instances normal use of the whiteboard led to hitting the cap.
In order to change the value (on per-server basis) to, say, 500 annotations in your deployment, add the following to `/etc/bigbluebutton/bbb-html5.yml`
```
public:
whiteboard:
maxNumberOfAnnotations: 500
```
and restart BigBlueButton via `sudo bbb-conf --restart`
