Post Author Text/Link (By XYZ)
It's more convenient if the "by" phrase is included in the link. It's easier for going to the author profile just by hovering on "by user" phrase. Probably the name is too short. For example, in the case of Chinese, there may be only one symbol as an author name, thus the hovering will be a bit harder.
However, as you may know, wpForo allows customizing the template and styles. So you can easily customize and remove the link from the "by" phrase.
The update-safe way of customization is described here:
I won't lie... there is no functional reason. I just don't like it and think it looks wrong because the name is meant to be the link, without any words before or after.
A good comparison would be:
The Google URL is http://google.com
To me that just looks ridiculous. However, whilst I think it should be changed, I'm not saying it is something you need to do. I'm more than happy to make the necessary changes and manually apply them after any updates.
Just would like to know from you guys where I have to make this change 😀
