I know why you've turned off all the extras, I hate scrolling past loads of tickers, pictures and sparklies that distract you from reading the message below.
Have a look at BabyFit though, they have limited what people can have and it looks really nice, there is a certain amount of personalisation without getting silly. They have no html in posts or sig lines, built in ticker to due date and an avatar.
I think that it can be nice to see who you are talking to or a picture of someone else's baby smeared in spag bol or eating meat with their hands (he he) and a single ticker, no sparklies, so people can show something important that interests them (I've been Baby Led Weaning for xm, xd!")
