I may have found an other possibly interested person.
Though he has a slight wonder of the playing level, being used to free and low casual.
But I said that as long as he tries to work with the at least 4 sentence rule, it should be fine, its like you said, make serious effort, but if someone cant come up with more then, I dont think it would be the end of the world as long as its not continual right?
meaning if someone would generally post 4, 5 or more, it wont be that bad if he/ she due to lack of stuff to work with or something post a two liner for once, as long as he/ she gets back to the more then 4 liners after that one time.
right?

beyond that, he could proof a great aspect, have been in a sci-fi rp with him before and though at first he came with something I was like:
okeeee.... how the hell will he make that work

I had my doubts as the concept was really off from what I had envisioned for the rp, but allowed it to see if it worked.
And i went great actually, one of the better creations in that rp.
so I know that as far as character build and contributions to the galaxy and rp, he will be a good asset ^^
well that being the case that he has no issue with going into a more medium casual setting and all that XD
