When I am not building products for my customers here on freelancer, I am a volunteer for the International Federation of Trekkers. Our organization, made up of multiple chapters spread throughout the globe where we celebrate Star Trek. Our main system that we use for Instant Messaging is Openfire. I have integrated Openfire with Wordpress, LDAP, and even with it's own authentication. In addition, I have integrated Openfire with other systems to allow websites to have "request Chat IM support" capabilities on websites.
I believe I can work your server relatively quickly and get you up and going. I am on skype, and will be available to work your solution immediately.
Thank you very much and I am looking forward to working with you.
