Yes. I'm using Opera 9.24 at the moment -- sort of a test period since I've started to find Mozilla Firefox a little annoying (no new features in ages, starting to feel a little sluggish in places, takes AGES to start up.. hrmph).

Now, Opera is really rather lovely but it makes reading forum posts something of a chore: the table cell that has everyone's avatar image in is the same size as the cell that contains their actual post, thus squashing all that wholesome text into a narrow column. Actually writing a post looks fine: it's just reading them that looks weird. I'm viewing in the default blue / white skin, if that's any help at all.

I must say, Opera is really rather nice, isn't it? Looks much better than Firefox, although there are the odd niggle or two. The most annoying is that the adblocker is several streets behind Firefox's ad-smacking kung fu. Grr.
