Vongeo and hoppy, this is still part of the upper fora.
As for larger avatars, I don't see a reason for it. Avatars are handy for quickly identifying a poster; however, they do get in the way. A larger avatar would take up more room and leave less room for text. This might not be a big deal if you have a large monitor, but on a phone or other small screen device, they are very annoying as it is.
Also, on my phone, avatars often take a while to load. Bigger avatars would just slow it down more.
In conclusion, I see no reason for larger avatars, other than to help Thork feel more powerful. If we were voting, I would vote for smaller avatars rather than larger ones.
