Hi Michael:
Thanks for letting us know. I for one is not too enthusiastic about the UBB image coding for the same reasons you listed on the announcements. (Sorry to everyone who liked those UBB images.)
Even though I access Webflyer on a T-1 LAN (cable modem and 56k dial-up at home), those images can really slow down the server, especially on long threads such as "who we all are" which is >300k in size.
In addition, having a # of the gifs on the screen while reading is almost as distracting/annoying as flashy advertising banners.
