Plus I think we all suffer from muse issues, which it sounds like what you have.  My muse has been a little emo brat this weekend so I have all these ideas flowing but I sit to write and no words come.  And English is my first language.  Like Sue said, it's kind of a balance you have to work out in group games.  I've not done much on here but I've done a lot of group stuff on other sites and it takes a bit to find a comfortable rhythm and figure each other out.
