It is super simple, not too complicated interface makes it easier for non-English speakers like me as my friends understand how this works very well which I appreciate that much. There really was no downside at all since we use it in our university community group in Japan, everyone knows what to do when there are scheduled activities. As far as problems go that people would be asking about here, nothing comes up with using this system at least from what I can tell while on campus during school hours. This will also help for those who work during office hours or want something to occupy themselves during such times. We have used this tool so many times now where students are able to easily make connections between themselves and others through social media networks. I like that it is so easy for me as an individual player, or coach/manager etc., to make use of this platform in my daily activities. It helps keep track of all things soccer related across my various connections! There are some glitches here & there but nothing too bad at the moment. As far as functionality goes - very good! Great tool if you're into sport management!!
