At the moment, before you do the upload, there's the screen that allows you to choose the events made by which players you wish to upload (sorry, that's a very ambiguous statement).
If you don't want to import events from someone, simply uncheck their name from the list and it'll upload.
At the moment, however, I won't be making an official fork of the Group Calendar mod yet. While that's in consideration for the future, it's not something on the immediate plate.
Hey Chops if your doing that then maybe there is a way you can automate it in the upload. If Player A is associated to Account A and is an officer assuming that on the Website you set privileges to the rank of officer and above to create events then it will be uploaded. If it isn't then it won't. This would save the person importing the information form having to weed thing outs and use the systems already in place on the site. If the Players profile isn't associated to an account and the account doesn't have a high enough rank then don't upload it.
