Hi! It's interesting to hear about your social community project. I have run my own community website since 2006 when it was first set-up. It really has been part-time whilst also developing using PHP/MySQL for other people to pay the bills, so I have some experience of online communities.
My site is a games website with just one game, Yahtzee. During its busiest period was fairly small, it had only 120 people online simultaneously during the evenings and had around 600 people each day. As I ran it I did the development (server management, MySQL, PHP, HTML/CSS/Javascripting etc etc) and marketing and SEO - we used to be #1 in Google - and community management.
May I ask about your project please?
What is the project and what tasks are you looking to have done? Are you looking for part-time/full-time and long-term/short-term?
Thanks very much, I hope to hear from you.
Please do respond even if I am offline, I will receive an email notification and will get back to you ASAP.
Thanks!
Sandy
