I have a website that is powered by script provided by elgg...([url removed, login to view]). I would like to add a yahoo/msn/gmail contact importer feature for inviting other users to join. This would need to be integrated with the current invite system of the site (the current system allows for only 1 email per invitation by keying in the email address manually.) Also I would like to have an integration with userplane's webchat and web messenger. Please bid if you ONLY have experience in doing this. Let us not waste each others time. Thank you.
