I would like to use a third-party module with my activeCollab Cloud account. Is that possible?
Sorry, it is not possible to use third-party modules on the Cloud. Only the official activeCollab add-ons (except the Source module) are available.
If you wish to use third-party modules, you may consider using the self-hosted version. You will be able to install any add-on that you wish, as long as it compatible with the your version of activeCollab.
