Firstly let me apologise for my error.
Secondly can I point out that I am on numerous mailing lists and bulletin boards, many of which permit HTML (and handle it properly). Therefore, every once in a while, I forget about the crap handling of subject lines on OpenACS and accidentally put a tag.
Oh dear....
What a earth-shattering slip-up that must be....
And now my mail box has five f***ing pointless emails arguing about it. Fix your software and stop bugging me about it.
Someone seems to have time to put on emoti-icons, but can't find the time to fix the header line???
