Notice that the "Reply to a reply" has a link to the reply that that reply is a reply to. However, this required quoting the reply to create that link. There should be a way to reply to the reply without need for quoting, but would still contain the link to the earlier reply that the subsequent reply is a reply to.
Note: If you would like your feature request / feedback about the forums to actually reach the "developers" (Wikia engineers), please submit it to Special:Contact/feedback. Wikia staff do not often read these forums, so they likely won't see your feature request / feedback here in the forums.
"Staff needed" is no longer being used in the new forums. You will need to use Special:Contact, as mentioned in the new forum policies (listed at Special:Forum, when you click the button at the top that says "Please click here to read forum policies before posting"):
If you need specific help from Wikia Staff, you can contact them at Special:Contact
To attract the attention of Wikia staff to a specific discussion, please use Special:Contact and include a link to the specific forum thread, with details about why staff input is needed.
