collaboration tools - for a little team (up to 25 menbers)

[dil_bert 5]

dear PHP-Freaks

 

we are much obsessed with collaboration, and the idea of successful teamwork - that ends up in productivity. 

We are aming effective teamwork collaboration in a little team - up to 25 members. i think that when teams have a good base of collaboration, they probably should be 
less susceptible to waste their energy and ressources. Well a strong base can be built trough the collaborative work of a little team. 

To be more precise: with the help of a good online collaboration environment that will not only help  us in productivity of a teamproject but also result in successful projects.

-  Trello
-  BitBucket
-  Github 

we re looking for online collaboration tools to take our productivity to somewhat the next level; We re looking for a free project management and productivity tool, as well as a powerful team collaboration software, 

with features like 
- subtasks, 
- reminders, 
- task priorities, 
- time tracking, 

nice to have: 

- Gantt charts, 
- goals, 
- dependencies and custom statuses, 

 

 

which way to go - what would you suggest. Love to hear your ideas and experience

That's asking a lot for a free service.

I can't speak very well of it, but Asana has a free version for 15 people.
