Over the past 15 years I've been involved in several open source communities.
CiviCRM is without any doubt the one that has the strongest focus in welcoming "newbies" and letting everyone feel at home here. Another impressive feature is the focus on shipping. No matter what you think of CiviCRM today, you are almost sure that there will be a newer and better version in a few months.
CiviCRM is a powerful tool for NFP's - small or large, rich or poor. The ease of customisation, huge feature set and great support forums make it possible for me to provide my organisations with exactly hwat they need.
CiviCRM is a powerful tool that could be really useful for many non-profits in Mexico.
Unfortunately the community is very small in my country. I hope that in the next years the community expands around Latin America.
I work for the Electronic Frontier Foundation. We switched to CiviCRM so that we could be sure that our membership data stays safe, secure, and private. Now we have control over our CRM and can customize it to work for our needs.
I'm working to support end users of CiviCRM and as part of team implementing and developing CiviCRM databases and related sites. I'm looking to gain a deeper understanding of how CiviCRM works and to learn from other people's experiences.
CiviCRM provides Future First with world-class database software for absolutely free. We use it to store well over 100,000 contacts with no signs of slowing. CiviCRM is so customisable that we can implement cool features without needing to reinvent the wheel each time.
If you like empowering charities in a free and open way then you are going to love Civi!
The community around CiviCRM is international, multicultural, friendly, sometime opinionated but always respectful and welcoming new ideas. It is a real pleasure to interact with these people - but see for yourself: dive in and ask your first question on the forums!
We thoroughly appreciate CiviCRM as a software and this community, and when helping our customers implement and make the best of CiviCRM we are always looking for ways to contribute back.
