Xtian, don't worry about your English, we are receiving you loud and clear!
I actually think it's rather nice when people don't have perfect foriegn language skills, it makes life a little more interesting and sometimes quite amusing. I remember well those wonderful posts of Godo and his use of English. We all found his stories hilarious, made funnier by his use of the language. This did not mean we laughed at him in a derogatory manner however, butI for one sat here with tears streaming down my face.
Like you, I found when I was in Germany, my language skills improved no end but returning to England and with the passage of time, it all began to slip away again. I also found it extremely tiring trying to keep going in a foreign language all day. I am certainly not brave enough or educated enough to attempt it on a German forum ,thats for sure.
I have to say, that when my foreign clients e-mail me apologising for their poor English, I always thank them for using it and point out that their English, however poor is a damn sight better than my German/Dutch/ Spanish etc etc.
You are doing ok Xtian.
