An approach is provided in which the approach identifies a set of active online meetings in which the approach identifies a set of active online meetings in which a user is participating. The approach dynamically computes an interest level of each of the set of active online meetings based on a set of user preferences to produce a set of interest levels corresponding to the set of active online meetings. The approach determines a priority order of the set of active online meetings based on the set of interest levels and presents the set of active online meetings to the user based on the determined priority order.
