No, and i have tried with friends. It's just too diffucult and to come up with an official agreement (not saying that I don't like to work with ppl, my friends and I make videos and podcasts together which I find awesome :D ) Besides, to me, it's easier -and más entertaining- to do it myself and then my friends and I will trade stories and read them over the weekend o something ^^
If i could find someone with a similar taste then I would amor to co-operate with someone because I have a big problem with beginning to write my stories after I get the idea....
So If he/she was interested in helping me then I would be very happy to have him/her.
Yes and no. I like the idea of escritura a story with someone (imagine how much less work you'd have to to!) but in practice it wouldn't work for me. There'd be too much arguing over the final say, and what works best, and all that.
I've tried with my neighbor but I was much más into it than she. Being completely one sided, I went on it alone and grew bored with the plot halfway in seeing as it was mostly her idea to being with. I tried again with someone online and this didn't work out just because we were at opposite ends of the world and were having a hard time meeting up to discuss anything. I'd really like to though. I think it would be something fun to try. I'm easygoing when it comes to plots. Unfortunately I don't know any writers. XD
