Hello to anyone who might be using the Algebra notation filter.
As mentioned in the news post Moodle core plugins review, we are currently reviewing the plugins in core with the aim of removing any which are no longer or hardly used, and if appropriate, adding them to the Plugins directory. Included in the list of plugins being considered for possible removal is the Algebra notation filter. Thus, please let us know if you have any reasons for wanting it to remain in core.
