First question is about linking.
I tried to make the following link:
and it failed to work.
Once I removed all the spaces, parentheses & percentage signs, it worked fine. Of couse my link didn't work because I don't have a file named "CXP-DisturbingPicturesEoEAMV.avi" on my server. I don't see why phpBB is stupid not to accept everything after the = symbol.
Second, I thought there was some a bunch of hoopla about a neato edit feature, which I have yet to find. There is a nice preview button, but I've yet to find the edit button.
