I don't think there's anything majorly wrong with reviving approved resource threads (it's much better than doing it in WE Help section at any rate), especially if a user is having a problem with the spell (even though I haven't seen hell_knight around the forum lately, so you mightn't be able to get help from him on this)
Do you need to import the lightning effects (check the Import Manager for the demo map, there might be a SplatData.txt or something, since those particular lightning effects are custom, I think)
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
