Hi Rohit,
Thanks for checking out our plugins!
Community Events allows users to submit events from the front end of your site, and you can control the default status of user-submitted events (ex: Draft will allow an admin to review them before publishing to the site). Community Tickets will allow users to sell tickets on your site as well.
Regarding changing terms, if you are referring to categories and tags, you are able to add these to events. If you mean changing the text where “event” is displayed on the site, that is also possible (we have an article on that here).
Events will have buttons by default to allow users to export them to a calendar, but if you wanted to add social media share buttons, you could use The Events Calendar in conjunction with a third party plugin that adds these buttons to posts, similar to this one.
While we do not currently do customizations, we do have a themer’s guide to help you if you would like to customize any of our plugins, and we also have a list of developers we recommend. Additionally, by purchasing a license for our premium plugins, you get access to our premium support forums, where we are always happy to answer questions, troubleshoot, and help point you in the right direction!
Please let me know if you have any other questions.
Thanks,
Jennifer
