I think a good way to get started is Duolingo which is free.
Also I think you can also use https://www.lingq.com/ I think they have Romanian
You can also find Romanian grammar books on Google and you could find a partner, a native speaker.
Good luck !!
I wouldn't worry about the reputation at all, each language has issues. I just focus on reading and listening, and try to get onto native content as fast as I can (then u can just read novels and watch TV etc and have fun).
Surprisingly, I have found toooons of things in Romanian, so if you would like any material, or have any popular authors you like, just pm me and I can send you something perhaps :)
Puedes encontrar a alguien que habla ingles o español y rumano. Puedo preguntar por que queren tu y tus amigos aprender rumano? No he oido muchas personas querer saber rumano.
