I am really sorry but unfortunately our support policy does not cover customizations as outlined in http://stackideas.com/support .

And even you want to customize this also will involve a lot of files that need to modify it.

But if your site user only access the event listing page click from the Easysocial toolbar, then you can try to download my attached file and put this file into this following file location.

JoomlaFolder/templates/yourCurrentTemplate/html/com_easysocial/toolbar/..

For those new folders you have to manually create it.
