Email Events Organiser button and suggest events based on user ip module/plugin

Hi,
1) It would be great if there was the option within each event to have a button connected with each organiser's contact email so that users can contact him/her directly (maybe through a contact form) with any questions they might have re the event (in my site i have different organisers uploading events so this would be helpful)
2) it would also be great if there was a module/plugin that could suggest upcoming events (or todays events) based on the city/area that the user has accessed the site from thus, using data from the user's ip to suggest events
Thanks.
