Gaswerk - English speaker

Hi Guys!
I am an Irish climber living in Zurich and would like to go clmibing in Gaswerk, Schlieren tomorrow (Wednesday 22 Feb) evening, after 6pm. Does anybody want to arrange to meet me there and take turns in belaying?
I have been climbing for many years in Ireland, Spain, France etc. and normally can climb at 6a/6b, but since I haven't climbed for a while I think 6a is realistic for me now.
