First off, thanks for the forum work. It's helped me and I've enjoyed my stay thus far. I don't want to sound ungrateful here.
On the avatar file size - is there any way to get this increased, or is this an option for those who are paying members? I only saw something about attachment limitations in regards to a membership. I run a forum myself and I understand that file space can be at a premium, but 6k? 6000 bits really doesn't get too much of a point across for computers these days. Even with 10,000 avatar pics you're roughly at 6% of one megabyte.
I'll even offer to host the avatars at my site if phpBB will even do that.
