Hi, We've had a couple of instances over the last day or so (on en wikipedia) where users signatures (that have naughty unbalanced html tags) are messing up the page. I guess one of the webservers doesn't have htmltidy set up.
Two of the users are in europe, one in the US, so ''maybe'' it's one of the european servers (I can supply deltas if that will help).
And yes, all the offending users are in the process of being hectored about sanitary html practices...
