Im not trying to advertise or anything. But you should use Parse (and the Parse plugin), because I think it is perfect for this job.
Thanks for the tip, goodfeet. I took a look on parse - and the firebase plugin from rex (had seen it somewhere linked in the thread).
Both look good, but the problem I have (personally) is, that its somewhere else saved (I hate cloud related stuff, because you arent able change some options, like you would have when you got your own databaseserver/ftp/etc). I prefer having the chance of options. Also with the limits, parse seems a bit high (for a hobby project) and I dont think that the free plan is enough with its 30 actions/second - and firebase only got a decent capability of storage & connections (except the paid ones).
Aim is having a register/login interface (and of course functionality, lol), a way to get C2 to download all the variables I need into the layout (directionary or an array), upload all changes whose were made to the variables - and a simple example of a query (leaderboard, get top values of (for example) strenght and show their IDs descending in a table).
As Im not that unskilled in syntax I really need a "quick and dirty" template of all needed components.
I may have someone who does this for me, but hes busy rigth now. So if someone has time and experience, talk to me
