Hi,
I just did this google calendar- originally to let people know when my stuff is, and then I added SAF & SIMF dates, and some others from Kirkdale Bookshop lists, and the plan is that anyone who would like their event on it can email me sydenhamevents@googlemail.com and I'll pop the details in.
It's quite possibly a meantime thing until we have a local events diary somewhere, and it's meant to be inclusive so anyone can let me know what's on & I'll post it (ok, within reason)
the google diary is here:
