I have a site, where there are more than 15 members are existing. Every one set their own calender event. But when i see the site calender, I am unable to know, who created this particular event. Though it is visible at "Site Activities" (current), it shows maximum of 28 days. Is there anyway, i can get Creator name along with other details, while click on particular event
There is no way to add the event creator to the event details display out-of-the-box. You would have to do this through a customization. I took a very quick look at what it would take to add this and it would not be that bad, but it does require customizations to the web scripts on both the repository and share tiers.
Also, you might be interested in this Add-On, which provides you with the ability to add "participants" to a calendar event. The add-on says it works with 4.0 and 4.1 but does not list 4.2 so it may or may not work with 4.2 out-of-the-box.
