Personally I’m against, I think it’s spammy and has little added value. The writer of the plugin seems to agree with me, bases on the first line of the readme:
Felling nostalgic of old VBulletin days? Wanna spam and flame like it’s 2000?
People on old CD were pretty reserved with signatures in my experience. The most “spammy” thing I saw were the small division banners people had:
While we’re on the topic of bringing back old features, how about spotlights? We’d probably need a custom extension, but it was a fun feature that also showed off the community at its best.
Added to custom css works perfectly at limiting the height.
The plugin allows for two signature modes. An image mode that lets you input any image url for your signature, and a full “editor” mode, that allows for similar editing to a post. I personally prefer the full editor mode, especially if we implement a height cap. The plugin by default is opt-in, but it can be configured so that it is opt out.
